Ok so this is pretty much pissing me off. I have a 92 Civic Hatch with a JDM d15b. Now it being a SOHC is not my only problem, the idle is fuckin up. It just started 2 days ago. Now when i start my car in the AM it idles at 3k!!!!!!!!!! WTF! Then when it is warmed up, it bounces from 700ish-2100. Keeps doing that all day.

Now the question is, what is it? And do not say IACV, cause i have already changed it 3 times. Its doesnt throw any codes either. So please, someone help me out!!!


Thanks,
Sean

check and see if you dont have a air pocket in your cooling system, if not then it could be the IAC, TPS or the computer.

Kana

Yes, it will idle cold at 3k and then when it starts to warm up it will go from 2700ish toright above 1k and keep doing that until it is warmed up. When it is fully warmed up it will either sit right at 2k or bounce off 2k and back down to 1k ish.

My car idles weird aswell... but I think my cam has a effect on that.

Check the air pockets on your car.

its either a vacuum leak or you have air in the system but air in the system would not cause this problem .......... but it might be your tps
