I believe that my AAC valve (92 Q45) is sticking. I used a form-a-gasket material when my paper gasket broke. I ordered a new paper gasket and removed the form-a-gasket material and installed the new paper gasket.

I think some of the form-a-gasket stuff may have gotten onto the AAC rod and it is now sticking.

With the form-a-gasket stuff and the replacement paper gasket i am getting a high and irratic idle. The car idles around 2k +/- 500 rpm. I will let it idle for a long time hoping it will come down and sometimes it does briefly and then goes back up.

Does this sound like something a sticking AAC valve would cause? Also, any suggestions on how to clean it or test it?

thanks

jeff

Let us know what other maintenance you have performed, particualarly as conerns the intake path and fuel system.

Is the screw 2.5 turns out from closed? Sounds like you may also have a vacuum leak.

Tell us about the chain gukdes so that we may sleep well.
