245 correct idle after start but high after use 200 1992

Bump.

I just want to keep this thread alive, because you bring up some very interesting questions. For instance, whether the car knows anything about the clutch. I'd be surprised by that. Also, that your ECU was probably changed, and at the least, investigated by someone leaving traces.

Another thing has me chagrined. One year ago this month I took some readings in an attempt to correlate the amount of air passed by the IAC as gauged by percentage of full open with the duty cycle. In doing so, I also noted its behavior with and without closure of the TPS contact, doing so by electrical breakout and not by moving the throttle. I can't find my notes. Just uncaptioned scope traces and pics of IAC valves.

Worth doing again, I think, but presently I have only -951s to play with, which I believe do the injector cutoff on decel, and the measurements I took were in the driveway, perhaps not those you'd get after VSS told it actual driving was being undertaken. Also, the cars I have with LH2.4 are automatics.

By posting this, I will surely find my notes tomorrow, right? That's how it usually goes. In any event, I hope you come back and keep this thread going.
