h22 loses power at high RPM's?

I'm noticing that my car has lost alot of its performance lately especially at high rpms.

I know you guys dont wanna hear this but its an example. Last night I raced my buddys stock Integra LS and he actually kept up with me (thats how bad it is) Anyways back on topic..

I had codes for egr and knock sensor. I knocked both those codes out by replacing the knock sensor and cleaning out the carbon buildup off my egr. Today I gave it a fresh oil change, new ngk spark plugs, and cleaned out the throttle body. Now I have no codes but it still feels a bit sluggish at around 6-7k rpms. Im not a motor guy but I'm trying to do what I can.

What do you guys think I should chase after next?

Re: h22 loses power at high RPM's?

if you have no cels id say . normal tune up stuff ( plugs properly gapped , wires , cap , button and seafoam never hurts dirty intake/vlaves can kill a motors power ) . could also be a bad o2 or a cat starting to clog up .. you dont happen to weigh 300 lbs and him like 130 soaking wet or somthing ? weight has a big effect on these cars ..

Re: h22 loses power at high RPM's?

you got good/enough oil in it? i dont know for sure but I think if you dont have enough oil that its pretty bad when you hit vtec and thats when you feel the loss of power right? just throwing something out there

well yeah I always been putting mobil 1 synthetic with mobil 1 or k&n filter for a long time. I always make sure its topped off because i know h motors love to consume oil.

Ive heard something about a fuel filter can go bad? thus having sluggish power at high rpm because of no proper fuel delivery? Should I try changing that?

Re: h22 loses power at high RPM's?

i wouldnt just jump to changing it :P lol, i dont know if there is a way to test AFR's other than getting an AFR gauge but those will be very bad if your not getting enough fuel.

yeah i know lol, you have to do elimination :P first of all do you always run premium fuel? maybe your injectors need cleaned out? maybe its the spark? i dont remember if anyone asked you about plugs and wires?

okay you just changed the spark plugs, were they spaced right/are the new ones spaced right, other than that i have no clue lol

yup that car had never seen anything else other than premium fuel. Like 2 weeks ago I put some new ngk spark plugs. about the injectors, i dont know, maybe i should run seafoam or that lucas fuel injecter cleaner that you put n your gas tank.

How about the fuel pump? has that had any case of going bad in preludes?

Re: h22 loses power at high RPM's?

i dont know, I would do a search on here of "fuel pump" and see what you come up with, and both of those sound good, what about your intake? stock or aftermarket? might wanna see if anything is clogged up or if its really dirty

I have an AEM v2 intake. I checked it yesterday and it seems clean, I also cleaned out my throttle body with some throttle body cleaner, but it still feels the same.. its like it lags, like you know the power is supposed to come at that certain rpm, but it doesnt. its like i make more power around 4-5k rpm then just when it gets around 6-7k it just starts cutting off it so weird. Like I've said i had this car for about 3 years already and so i know how my cars supposed to feel, and it definitely doesn't feel right

Re: h22 loses power at high RPM's?

yeah i know what you are taking about lol, i dont have anyclue what could be causing this, maybe some smarter people will see this and be able to help you. Like i said I would search "fuel pump" and see what that comes up with. because your either not getting enough fuel, air, or there is a small cat in your exhaust lol

Re: h22 loses power at high RPM's?

2 things I can think of,
1. Check your dizzy cap, and make sure that the terminals on the inside are not excessively worn and the rotor is in good shape. Make sure that it is clean on the inside too, but don't clean it if it is dirty, get a new one.

2. Fuel, lack of fuel pressure ether by a stuck open FPR, clogged fuel filter, or your pump has resistance in the ground/power.

Is it misfiring at the high rpm? kinda like a rev limiter, or is it more of just no power.
If it just no power I would lean toward checking the fuel pressure, cause you are running lean in the high RPMs, while staying in range every where else.

Back probe the o2 at the ECU with a DMM and measure the DC volts as you are driving. You can do this too with a OBD2 scan tool. If you get low voltage, <.2v at the high rpm you know you have a lean misfire. If it is rich (high voltage, >1v) you know you have an ignition misfire.

no its not misfiring or rev limiting or anything. Its just the lack of power im feeling and its not only at high rpms, but its just more noticable at high rpms.
I will definitely check the dizzy cap asap tomorrow. And for it running too lean, what can make that happen? Its a stock ecu and i never tuned it. so maybe its because my mods (aem v2, hytech header, test pipe, greddy catback) are the cause if it running too lean maybe?

check your fuel pressure. rule out all the simple stuff like ignition, fuel. check all of your sensors as well

so here's my lil history with my lude so you can get an idea of what it might be..

... Bought a 93 h22 prelude.. everything was fine. vtec hit and everything (no jerking).. then a month later, bought a NEW "JDM" H22 w/ vtec motor.. had it professionally installed of course.. came out the shop, went on the highway, decided to hit vtec, the vtec had hit but it started to jerk as well.. i thought it was odd so i also thought i had to break in the new motor (lol) stupid, i know.. couple weeks went by with putting in 300+ miles on the motor.. (note: the new motor had "0" miles) =] anyways.. the vtec was still jerking my car, so i searched around the net and one solution came up, the soleniod might be bad.. i bought a new one and installed it... well, it STILL jerks, the solenoid was not the problem.. i called the shop who i had my motor installed and they said it might be the fuel filter as well.. "since its a brand new motor" they also said that its puttin out "lean"..?? whatever that means.. lol shed some light on that for me please.. anyways..

thanks again guys!!

--> EDIT: Went to Texas, had them check it out... Fuel filter was dirty, so i bought a new one to replace it.. they installed it and everything. SAME PROBLEM! they told me that they could trouble shoot it now since the filter is new.. I'm most likely going to have it trouble shooted to know what the exact problem is.. It HAS to be something small.. Im really thinking it has something to do with "fuel" i know it aint the fuel pump and the fuel filter now.. im thinking it could be the fuel injectors.. maybe those are clogged..?
sounds like you may be having the same problem as them? id be interested in finding out whats wrong with theirs also.

Re: h22 loses power at high RPM's?

Ok I dont wanna bring it up but My H22 was doing the same thing, it was losing power at mid to high rpm and I figured it out. Yes U did the right thing by cleaning the egr valve but their are ports in your intake that clog up and rob your engines power. This is what i did and its fine but dont do it for long, ok disconnect your egr valve plug and drive the car, yes You will get a code but your car should run better and its fine, lol i had mine disconnected for mad long before i fixed it..the dealership didnt even know wat was wrong wit my car but i did. If your car runs mint its your egr ports in your intake thats clogged, its a known H22 problem. You can get it cleaned or replace the intake, its up too you, ight man good luck.

by intake he means intake manifold, and the fix is like $20 and a couple hours if you wanna do it, rather than like $300 for a new manifold... I have the same problem with my lude but it caused me to misfire, so idk if its the same thing for you, but yeah i am still driving around with my egr unplugged because it is too cold for me to want to work on my lude and i might be getting an aftermarket intake manifold for some more power anyways.

Re: h22 loses power at high RPM's?

its a gray plug on the egr valve just unplug it, ull see it its right on top of the egr valve. if your lookin at the engine its on your left next to the coil, its a small little connecter. when u get the code for the egr being unplugged just ignore it, if your car runs fine threw the rpms it the intake manifold ports. You can run the engine but the annoying C.E.L will show.

Re: h22 loses power at high RPM's?

the new intake manifold will fix it if its that, like he said just unplug the egr valve and see if that does anything and if it does get the new manifold or do this: egr port cleaning

ok so lets say it is that, do you think getting a euro r manifold (one i always wanted) could fix the problem?
