Hesitation When Accelerating

Hey Guys

I know theres threads that cover this but I have a very specific problem im trying to solve.. so here goes:

Firstly, my car has a JDM H22A and JDM type distributor (internal coil). The car starts and idles fine but when im accelerating quickly, its sluggish (most noticeable up to 3000 rpm). I get CEL codes for misfires on all cylinders and when I clear the ECU its gone for a little while.

Took the car to Honda and they could not (in 2 hours of labour) figure out the exact cause as they could not apparently get the misfire to reappear. They just listed that it could be: ignition coil, distributor, spark plugs/wires, fuel filter, valve lash, injectors, or engine PCM.

The spark plugs and wires are new and as far as I know, the distributor has been replaced less than a couple years ago. The valves were adjusted last week. The fuel filter has also been replaced a 1.5 years ago. I tried unplugging my EGR and driving around to see if its any smoother and there was no difference. Did the same with the vac hose on the fuel pressure regulator - no difference.

Since its happening on all cylinders, im assuming its the distributor/ignition coil or something fuel related.

Any ideas?

Re: Hesitation When Accelerating

Listing the exact codes that your car is throwing would help greatly in this situation.

Just relaying what the dealership is telling you doesn't give us much to go off of.



If you're getting a CEL for a cylinder misfire, resetting it and driving off - That's one of the WORST things you could do in this situation.

im not saying I do that - just saying that temporarily makes the code go away

if I read the CEL blinks with a bridge in the service connector, I get codes 71,72,73,74 one after the other so that as I understand is misfiring in all cylinders

Sluggish when accelerating? You need an iron feet and some new kicks:)

Re: Hesitation When Accelerating

How many miles? if over 120k than maybe you need to have your egr cleaned.


Like you said - just start from the top and check plugs - plug wires - dizzy. Then move onto injectors and lastly fuel pump.


If you have a friend nearby with a 'lude, it'll make it easier so you can just swap parts to see what the issue is vs buying everything all over again.

Re: Hesitation When Accelerating

My car did the same thing...turns out it was the cap and rotor was shot. replaced both and the car pulls to 8k perfectly, good luck.

if I unplug the connector for the egr, shouldnt the car run better (assuming its clogged) or will it still produce symptoms if its stuck open?

Re: Hesitation When Accelerating

Okay so I have an update on this. I pulled off my distributor cap and this is what my rotor looks like



Im no expert but that looks pretty bad to me (sorry I know its blurry)

Here's my distributor cap


It doesnt look to worn, there was just some debris covering the contacts.

Anyone confirm that the rotor is shot?

Thanks

Re: Hesitation When Accelerating

i've had a similair problem... you can first start off by taking care of the CEL codes like everyone stated, then wat was my problem was that the ground wire from the fuel injector wires was loose. Its screwed on with a 10mm onto the manifold, You can tighten it if its loose or replace the wire... maybe about $12 at autozone.. hope this helps

fair enough. only had the car 2 months but the previous owner did replace the whole distributor. it doesnt look like the rotor was replaced. does it look pretty worn to you?

Re: Hesitation When Accelerating

maybe it's just a bad picture but it looks like there are tons of deposits on the rotor and the post that the rotor comes in contact with on the cap. looks like it's not making good contact. that is what will cause excess deposits. yeah most likely that's your rotor.. especially if you know for sure the previous owner didn't replace it.

Yes, those are bad contact points on both the cap and rotor. Replace it and see what happens, it needs to be done anyway.

As for the EGR, yes, if you unplug it and it runs better then that indicates the EGR is causing problems.

Re: Hesitation When Accelerating

Good news! So it definitely was the rotor/cap. My engine timing was barely off as well so had that adjustment. The car accelerates much smoother now

Thanks guys!
