So i have a 95 Integra with a B20B Swap.. The idle is going up and down.. Any Suggestions? I have been looking for a Vac-um Leak, Put a nipple on one.. But any help would be greatly appreciated.

Thank you

 

Does it do it only at idle?

 

probably the iac

 

2x on the AIC, but would that throw a code?

If it's not only at an idle, it might be an o2 sensor. In my old d series the RPMs would bounce.

 

It doesn't do it all of the time.. just every once in a while it jumps up and down from 1000 to 2000 or from 1 to 1500.

 

IAC. And I dont think it would throw a code. It might. My friend's 3000 had an IAC problem and it didnt throw a code. But then again.... It was pretty fucked up.

Any other symptoms? Hesitation? Sputtering? Loss of power?

 

I do notice a little hesitation. Maybe 02 censor?

 

Sounds like it...not sure if it's the same as the Ford ones but you can pull it and clean it

 

Yeah everyone here at the shop has said the same thing, "IAC" Because its not doing it all of the time. Just when it feels like it. Also, its not throwing off any kind of check engine or anything. So I will try and clean it out and see what that does for me.

Thanks for all of the help and replies!

 

dunno if cleaning it out will help or not as they have like a spring in them. my old ek had the same problem but threw out a p0505 code for it. it would kick a little when i shifted and hesitated a little. new IAC=150ish or so.
