acura90integra, can you give a little more detail?

 

When I first start my teg up in the cold morning it idols at about 2000 RPM. Then after a little while running it calms down and stars to idol at about 500. My mechanic says that this is perfectly normal and that it's just the car "warming up." Mines done that ever since I've gotten it and I've had no problems with it. Trust me, it's normal.

 

I was told that the 1.8 ltr honda dohc in the teg's Air intake control valve goes out alot causeing the engine to rev and de-rev at idle when cold. Is this correct and where is the Air intake control valve located? is it on the TB?

 

I checked for Air intake control valve at advance and a few other places and there is not any aic valve at these places. Is there any other name for it?

 

You should verify what the problem is before you go off and buy a new IACV. If the idle is only messed up when the engine is cold, the most likely problem is the fast idle thermo valve. Here's the troubleshooting page for it out of the shop manual.

 

Where do u get those repair manuals from? Did u scan it, or use a website?

 

Someone scanned the 1993 Integra Helms manual and posted it online a long time ago, I downloaded the whole thing. I would put it online if I had enough web space but enfortunately I do not and all the files are over my ISP's size limit of for outgoing emails.
