My 90 5-speed had been running and idling well when that 2000 rpm miss started happening (again). I recognized it as the TPS being out of adjustment, so I adjusted it and everything seemed ok.
A couple of days later it started the high idle thing (which has happened before as well). So I checked the TPS again and the number had dropped from the .825 to .7something, so I adjusted it again, but the idle never got better.
Within the last 3 years, I have replaced both the TPS and IAC, but am suspecting a bad IAC again.
The idle is normal to low at start-up and was going up to 1300 after warm up. I took the IAC out yesterday to inspect/clean, but it wasn't dirty. After re-installation, the idle is very low on initial start up and now may go as high as 2000rpm, but verys with every traffic stop. When I had it out (but electrically connected) I turned the key on and it did not move.
Do I have a bad IAC again? How do I know for sure?
Thanks,
Scott
