I bought a 1996 Buick century with a 3100 engine. It's idling very high. I changed the IAC valve. This took it down from 2400 to 1400 RPM's. It's supposed to be 700. It's not throwing a code. All the parameters check out with a modis. There are no vacuum leaks, I checked around the intake and injectors with starting fluid (dangerous I know) and all hoses appear to be good. It looks like (not positive) someone change the crank sensor. Any ideas? I wasted today on it, and it's becoming frustrating.
have the same problem?
