1989 Cavilier, 107000 miles, 4 cylinder 2 liter, automatic: Car has been stalling when low RPM, but no codes up (engine light is off) and none in the computer. Weather is cold (-30 to -40 Deg F) Stalls when idle at red light or turning corners. Sometimes at the red light taking off I could tell there was a miss to the motor, and lack of power. Did not do this all the time, but frequently. Took car inside heated shop and checked plugs, all clean and firing. Found no wires damage. Found no obvious problem with anything esle, all looked ok (no vacuum leak, gas leaks, etc). When I ran it after, the problem went away for about an hour. It started with the car in 3rd gear, at low RPM, car would (studder) but when placed to second this went away as RPM increased. I am wondering if this is possibly a bad wire (shorting occasionally) or the ignition module failing? Or something else?
