I have a 1994 4door integra. My engine seem to idle low and then high. It dose not do this all the time. Somtimes it normal and sotimes it starts doing it. It seems like the engine wants to turn off ,the idle will drop and then go up constantly. Dose any one know what this could be.

 

there should be some kind of valve thing behind the intake manifold that being held down by two 10mm bolts i think its the iac valve (idle air control valve). Well any ways some people clean it with brake cleaner or simple clean and in short for them it helped. Try researching using the key word "idle" and your topic just might arise.
