Has anyone ever experienced their IAC going "bad" on an SN95. I have been having numerous problems with my car idling (with a Speedbrain computer), and it is appearing as though the IAC on my 95 might be bad.
It seems like no matter what I do to the car, it will not find a steady idle most of the time. No matter how wide I open the IAC screw, the car falls back to idle VERY fast after pushing in the clutch, and nearly stalls. Also, within the Speedbrain, I have done some datalogging at idle. It shows the IAC position as a percentage of how far open it is (I think), and across the entire datalog (all of the ones I've done), it reads 0. Everyone I've talked to says it should be reading at LEAST something. I have adjusted the IAC screw to various locations, and it STILL reads 0. So it's not something where I've got the IAC screw open too far and the IAC itself is staying closed to compensate. Also, I now have the screw nearly completely closed. This is the only place it would find an idle.
I'd appreciate any input. I don't want to buy a new IAC ($80) if I don't need it, but have no problems purchasing one if it's the problem.
