Car hesitant..help

I notice that when i am shifting into second (mostly second) that when i accelerate it doesnt accelerate as much. but then about 2 seconds later itll have more power. it is like a sudden power increase.

Could this be the clutch slipping?

Thanks
Brad

Re: Car hesitant..help

feel almost like a mini-vtec? if so, i dont think its the clutch cause mine does that too sometimes, but mostly when its not warmed up. and mines an auto

With only the info you have given, sounds like your clutch is slipping. Or driver error

Re: Car hesitant..help

If the clutch was slipping, wouldn't the RPM's be increased a bit til it grabbed, kinda like riding the clutch out?

Sometimes my acceleration feels like the power hops up in stages, but only if I'm flooring it starting at 1500rpm when I'm trying to make the doosh in the TC next to me feel like even more of a doosh for thinkin his TC is cool.

Re: Car hesitant..help

maybe the timing is off by like 6 degrees does the engine sound like its struggling or is it just reving then grabing

Re: Car hesitant..help

having the same problem here, had its oil change ( 10w40 ) right before I bought the car and it used to pull very hard between 3000 & up.

now it seems when I ''floor'' it @ 3000, it pulls wayyyyyyy less and vtec engages but not has hard as before. oil level is good, and I have brand new NGK Iridium IX spark plugs. some other thing I noticed was that when it's cool outside, let's say from 5c to 15c the lude has all it's power.

I came up with some things that could change my car's behavior :

- hot weather
- old spark plugs wires ( need to change 'em )
- dirty air filter (was dirty when I bought it tho... )


if someone had the same problem, please share, I'd like to have my lude peppy again !!

edit : ex-owner used to fill up on regular gas, I switched to 91 octane from the day I got it

Re: Car hesitant..help

sounds like the infamous h22 lag/drag. try doing/getting a valve adjustment, seems to have cured my occasional lag around 3k rpms (knock on wood).

also u should def get some fresh filters in there (don't forget fuel filter if it's been ~60k miles), and check/replace plugs and wires.

Your timing could be slightly off, did you recently change anything associated with timing?

Re: Car hesitant..help

Oh...I thought this was more of a clutch related problem. Now I see it a little differently. Dude, my car pulls crazy hard at 4k (non-Vtec). I just assumed it was the Prelude's "Butter Zone." Every car I have driven has a certain RPM where it gets some real power. I guess it could be a problem, but I say it's just the "power band."

Re: Car hesitant..help

I didnt change anything at all with timing, It's bone stock, well ( h22z1 base w/ original h22a4 head )

I just came back from work and noticed that it was all random, I could go from a green light and it would pull like it should, and some other time I would almost have to rev it up to 4.5 K to get it going ( strong )
On the high way tho, even in 5th gear it feels very strong ( good air flow ?)

I really dont know was it the problem, soon to be changed :
- air filter -> K&N drop in ( can't find any here in Qc )
- new spark plugs wires

and if it continues then I'll go deeper with; fuel filter, injector cleaner and all that stuff

it really frustrates me that it's totally random

Re: Car hesitant..help

bump,

today was horrible, at a green light I could barely pass vini-vans while shifting a 4K...

from 3K and up til vtec I had very little power ( vtec too felt poor but always kicks in )

can't wait to get my new wires & air filter on tuesday, I hope it will solve my problem

Re: Car hesitant..help

Im also having the same problem. The car can barely get out of its own way, and vtec seems like it doesnt 'hit' as hard as i used to. Ive had the problem for months now and have since done a valve adj, fuel filter change, plugs/wires, and a fuel pump to no avail.

Re: Car hesitant..help

my car does the same thing, but my timing is advanced, the engine is pretty much shot and there's a bolt missing from the clutch master cylinder. Clutch is getting fixed tomorrow, and I'm getting a new engine soon. (Last owner beat on it before it was broken in, has no real power and leaks oil everywhere.)

Mine's almost brand new, although it is the cheapo autozone/spectre brand or whatever. I really doubt that's my problem. I'm thinking it could be a malfunctioning sensor or something because it runs rich big time when floored.

do you have any CEL's ?
could be EGR messing up or a clogged cat

edit :

here's what my filter looks like

sorry about the pic being a bit blurry, but it's dirty as hell lol
I test drove it with and without the filter and I could feel a big difference, without the filter It would suck much much more air in,
with the filter, gas pedal was kinda hard to press down...and slow to rev..

Re: Car hesitant..help

I managed to fix mine.

In short, it was my factory fuel pressure regulator.

Not entirely sure how or why, could be old age of components etc but my lude had some characteristic hesitation features:

Fine when cold, once really warm it feels like it's not pulling but simply being forced to pull.
I used to have trouble getting up minor hills, torque just wasn't there.

The only changes that occurred for me between stock, which felt fine and the hesitation is the following:

Newish dizzy (low km) and coil
Iridium spark plugs rather than platimum
Aftermarket vision ignition leads (low resistance etc etc)
Field air fuel controller
Custom CAI
New aftermarket rear muffler (powerpro)

I dont have a dyno graph of the stock set up but I do actually have video's/sound clips that can confirm that things actually got slower as more boltons were added.

Finally got onto a dyno, last year, hoping for atleast 120wkw, got 95wkw. Hmmm, not good.....
After a few months of research and carefull analysis of my air fuel ratio, I narrowed it down to my engine simply not getting enough fuel, obvious really but I had to eliminate other problems (Clogged CAT, clogged injectors etc etc)(it was sitting around 13.5 below 4k and at 14-14.5 around 4.8-5.5k rpm, after that my air fuel ratio craps out to 11:1 at 7.2k rpm). Air flow improves with boltons and for some reason the stock system cant compensate in my case.

Click here to see my dyno plot (members rides)

I got a new fuel filter, didn't seem to change anything (stock filter was dirty but still functional). Then I swapped out the factory fuel pressure regulator for an aftermarket one. Set the fuel pressure to around 45psi without vac, car wouldn't start initially. Dropped the pressure to 42psi and it started and sounded great.

Since then i have "tuned" it but I still dont have a dyno plot to prove things are restored. What I do have is bum dyno! Car feels great, fuel economy has dropped a little but I currently have my fuel pressure at 41psi (no vac). What I have noticed:
I can now take out fuel with my fuel controller, which is great (I was lean before so couldn't do a thing...)
Taking out fuel increases ignition timing, couple that with a good ignition system and more fuel= POWER.
Hesitation wise, there is no such thing any more. Even after sitting in bumper to bumper traffic for 30 min the car still pulls like a dream.
Torque at low rpm has dramatically increased, I loose traction at 2.5k rpm or 5k rpm if floored (6mm on both front tyres) and in wet weather I have no traction at WOT in 1st, lol, and I am in an auto!

Therefore in my case I needed fuel. Cant generalize to all preludes (Mine is a JDM BB1), but in my case the factory system couldn't deliver, all that was needed is a little more fuel (fuel pressure is at the top of factory range now for an H22A).

So my theory is that the factory fuel pressure regulator becomes lazy over time (spring looses its tension maybe???), which results in fuel pressure sitting in the lower area of factory specs (35psi with no vacuum etc), which means there is engine knock when warm (air fuel ratio too lean), resulting in the ECU pulling timing and giving the hesitation when warm feeling!

Something I thought I would add, preludes are known to run rich at WOT, but what about the fuel and ignition settings at partial throttle? I would assume the factory maps are set for economy rather than power at partial throttle so if one would alter the factory designed system (free flowing intake and exhaust) then at any given MAP signal the amount of air being drawn into the engine will be more than what honda initially engineered/planned the fuel/ignition maps for. Therefore, increased air flow will not necessarily be compensated for my increased MAP signals for at any given MAP and throttle position there is more air flow than what MAP was initially mapped for. Therefore it could very well be that the engine is running lean at partial throttle (hesitation) but still running fine at WOT.

Sorry for the ramble; feel free to point out mistakes, bad assumptions etc etc.lol

Re: Car hesitant..help

The problem with that theory is that my car was almost bone stock beside an AEM SRI that came with the car when this problem started to occur. But i do think that you may have a point with the fuel pressure.

Did you test the original pressure reg with no vac?

Re: Car hesitant..help

No I didn't have a connector that would permit me checking the stock fuel pressure. I still have the stock regulator and its easy enough to switch between the two, maybe ill do so at some stage. New dyno plot would also be handy, can do runs with varying fuel pressure and to see what fuel pressure replicates my previous plot.

But interesting that your problem only occurred after improving air flow! Really need wide band and a way to record the readings after just driving around with some moderate throttle.

The VAFC2/SAFC2 can actually help prove this theory as well. Not sure how accurate their knock sensor feature/conversion is but its simply getting its signal from the stock knock sensor and therefore one can see if there is knock at partial throttle or full throttle. If there is knock, you are running too lean, but its only at partial throttle (not as bad), therefore the ECU pulls some timing, engine feels hesitant car appears to be running rich due to unburnt fuel/pulled ignition. May be a bit far fetched but who knows. Really wish I had an VAFC2/SAFC2 right about now.lol.

Re: Car hesitant..help

alright, I just installed new plug wires ( oem ) + New oem air filter

car ''seeeeems'' to run better

I have the stock ''Y'' pipes removed from my intake, I absolutly hate the sound it provides so I'll put it back tonight and see if my car pulls a lill better

( as far as I remember, even with old wires and old filter it still pulled harder than now with the ''Y'' pipes removed )

yet again, maybe it's just me...

If problem still persists I was thinking :

- change fuel filter ( I got the original one, 128 xxx km )
- check timing belt
- maybe check fuel pressure regulator as ''MilanoH22ALude said'' ( I doubt it tho ) but thanks a lot for the input dude

-..... running out of ideas :/

Re: Car hesitant..help

im glad i saw this thread.. i always thought that my car was just pulling harder when it was cold because i hadnt been in it in a day so i forgot the power.. but now that i think about it after it warms up it just dies on power and crawls around everywhere.. im very interested in any answers so im in on this thread with you.. i just thought that thats how my prelude is.. no power until about 4k then like a powerband almost.. but i realize that its not like that when its cold.. i always love driving it when its cold so much more then warm.. im going to start researching this.. i want to help me and you out!

Re: Car hesitant..help

so I just came back for a lill ride with my ''Y'' pipes re-installed
( those pipes are actually the Cold air section of the factory intake )

here's how my situation improved:

- absolutely no more hesitation, rpm needle increased steadily without bogging whatsoever as I gave it gas

-little increase in torque as I had re-installed my intake, could feel the pull at around 3.5 K

-awesome highway power, ( it has always had )
- HOWEVER... after a long drive, let's say 30 min of highway, the car doesn't feel as strong as when I first drive it... still need to check out on this...

I'm a little relieved that I'm not the only one having this prob, stay tuned on this topic

Re: Car hesitant..help

Wow...that might be the reason my engine is such a piece...hell, I might not have to replace the engine after all...

Although I still prolly will, then do this anyway....my engine still leaks like a sieve...


However if I can find the leak and fix it (hopefully not the rear main again) and fix it then get a new fuel pressure regulator and fuel filter my problem might be fixed. Of course I'd have to compression test it to make sure the engine is actually good.

Wow, I might have just saved a couple grand and a lot of hassle buying and installing a new engine, money which I could use to buy a whole bunch of new goodies for my car. Only problem is, if I do this it might not leave me enough time to buy a new engine and install it before I have to go back out to school...so it's a gamble especially if it doesn't work.

What do you guys think???

Re: Car hesitant..help

i feel like the problem isnt the engine but the components around the engine.. and also when you guys are refering to the "y" pipe of your intake your talking about the intake resonator correct? If so i DO NOT feel like putting that thing back in.. it was a bitch and a half to get out.. its gonna be ever harder to get back in.

Re: Car hesitant..help

well the 'Y' pipes I'm talking about is actualy this part : ( forget the little valve, the Y pipes are the cold air intake section, plastic )



not to be mistaken with the actual resonator :



today was no good news for me, the car still pulled like ass,

@t 3000 rpm, my old 96 dx civic felt more peppy...
my lude seems to be forced to pull when I press down the gas pedal
I might add a little bit of oil tonight, ( noticed I was kinda low )
will see if that helps

@ dannelson : did you do a good tune up recently ?

like in any other troubleshooting, there are steps in finding the problem

I say start by cheking you ignition / spark splug etc..
them go with your filters, ( air, fuel... )
after that come back here and we'll try overcoming that son a !@#$% lack of power trouble so we can get our ludes to pull like they should
