Okay, before I get started.. I've read the FAQ about idle issues, I've done EVERYTHING that it's said. and my car still idles funny. For the record, this is the same engine I was having trouble with, it was firing on only 1 and 4. I fixed that, cleaned my EGR ports, and valve. But, now when I start the car, it runs fine.. But it kind of sounds like.. I guess you could say it has a lobe to the idle.. Then when you rev it, it'll idle down to about 300-500, want to die, but it won't, it'll just slowly idle back up, or if I give it a bit of gas, it idles fine. I was wondering if maybe it could be my injectors, or if it could be the ECU? The engine is an F22B1, the VTEC is not wired, the ECU I'm running is the P14. I'm not sure how to tell what injectors I have.. I'm extremely happy I got this running, but want it running excellent! Someone, could you please shed some light on this?

 

Bumppp.

 

bumping your own thread in just a couple of hours wont get the answer any faster.

have you checked your IACV? have you tried adjusting using the idle set screw? do you have an aftermarket flywheel?

 

I bumped it because in those few hours it was already on the second page.

Yes, I've checked my IACV, cleaned it, and cleaned it again. No, I have not messed with the idle screw, it idles fine at first, then will go down so I didn't want to mess with it. No, I do not have an aftermarket flywheel.

 

The p14 ecu is for the h23a1, probably at least part of your problem right there.

 

Well, I figured that. But when I bought the car, it ran fine with the P14. When I got the car all running again, but shitty idle, I went to the junkyard and picked up an ECU out of an Accord, with an F22B1 in it. The ECU is a POA? Not sure exactly what it is..

If this helps, witht he P14 first in the car, I was throwing I believe a code 41 for CEL. Once switched to the "new" ECU, my CELs were 3, 9, 14, and 21. I re installed the P14, and now I'm throwing an ECU code..ha. So, I'm dumbfounded yet again.

 

Get the correct ecu for the engine you have, and than fix any cels that pop up.

 

I was informed the P0A is the right ECU, now I have those said CELs:

3 MAP - manifold absolute pressure sensor
9 CYP - cylinder sensor
14 IAC (EACV) - idle air control valve
21 VTEC spool solenoid valve

I understand the code 21, my VTEC isn't hooked up. My map sensor should be good, I bought it from a reputable guy I know who assured it worked. CYP, I don't have a clue what to do.. as is with code 14, the IAC valve.. I've cleaned it and cleaned it, yet the problem persists.
