h22a idle problems

[92accordh22a]

I've got a 92 accord with an h22a swap and having trouble with idle problems.
When coming to a stop, I push the clutch in and shift to nuetral. The idle hangs at about 2200 rpms until I have come to a complete stop for approximatley 2 seconds. Having trouble figuring out the problem. Any advice will be greatly appreciated.

Could be a number of thing including your idle valve or egr valve, also, what ecu are you running for the h22?

[92accordh22a]

I am running the p13 ecu on my accord.

Check your TPS check engine light. Being a cel, that's usually where you'll want to start diagnosing.

Also, the "spoon chipped" ecu, unfortunately, is basically not a legitimate ecu. Replace that with a stock p13 or a chipped and properly tuned p28.


Those would be the first two thing's I'd look into before replacing too many more components. It might turn out that the ecu and tps are fine, but both are a little fishy and probably deserve recognition.

Good luck with it, idle problems are always annoying.

Hey was wondering if you got this fixed? I am currently beening having this problem and have been unable to come across a fix. As I drive, shift to N, the revs remain at about 1500-2000 until I come to a complete stop only then after 2seconds does the idle return to normal...

I have tryed checking vacuum lines, seem ok. Check fiv, checked egr, check tps, check iacv, all ok, running usdm p13 on jdm h22a swap(was having the same problem with the p13 jdm computer so I know for a fact is not the computer)

and I am not throwing no cel.....

same prob.

i have da same problem but i dont know what da hell your talking about . all that mumbo jumbo

[jakesh22accord]

My best bet is its your computer

I had the same problem up untill a few days ago.
I replaced My IACV my FITV my TPS shit i even adjusted my valve's.
Checked all over for vaccume leaks.
It was the stupid computer.

[90blackcoupe]

I have tryed 3 different computers, hasn't fixed it.

[90blackcoupe]

still no fix

[Saidaigen8]

it sounds like ur tps just needs to be adjusted.

make sure you check your coolant level too....this has been know to cause that to happen.
