i have a 93 saturn sl2 that idles rough at start but then it levels out to about 1200 rpm. that is where it remains to idle. when i give it gas from a stop the idle drops and it almost stalls. i have changed the ect sensor(there are two sensors and the one i changed was the one closest to the front of the car, was that the right one?), the fuel filter, the spark plugs and wires, the coolant temperature sending unit, the throttle body injector, cleaned out the throttle body, changed the powertrain control module, and am still having the same problem?
Optional Information:
