I've got an intermittent idle problem with my 89 5-speed. Seems to occur more frequently when the car is warmed up but it doesn't really matter. The idle will sometimes just stay at 1500 rpms and not come back down. When its having this problem while driving, its like the cruise control is on when I am going down the road.
This morning I got it to do it on me and I changed out the IAC sensor and the problem still persisted the same as before. After changing the sensor, the check engine came on for a second while driving.
At this point I have checked the codes and they are as follows: 49 spout signal problem, and 63 Throttle position circuit fault below minimum voltage. I checked output voltage at the TPS and it was a .9 at zero throttle and increased voltage smoothly when slowly opening the throttle. I adjusted the sensor to .97, its at 4.73volts at wide open throttle. Road tested car, Problem still persists.
I believe the tps code is being set because of the idle problem, and I have no clue about the spout signal code, the spout connector is plugged in. I have heard of someone having a problem with their spout connector going bad, is that a possibility?
Lastly, I cannot find any vaccum leaks. Being that the problem is intermittent I don't see a leak being a problem.
