After fixing the missing and sputtering problem my '92 2.3 had by replacing the injectors, now it has a terrible idle problem which started right before the injectors were replaced and now is gradually getting worse. The "Check Engine" light pops on and off every time I drive the car, and when I come to a stop, the RPM's will drop to about 500 and the car almost dies and then they kick back up to about 900-1000 RPMs and the light goes off and the car is fine. It does this EVERY time I drive it now, and it's gradually getting worse. Today the light stayed on for about ten minutes, and I stopped and let it idle (while I was looking at the price on a 5.0 Mustang, haha) and the car was just struggling to keep itself running. Then I got in the car, put it in gear, and drove off and the light turned off and the car started running fine again. Only a couple minutes later the light came back on and the car started lightly jerking at about 75 MPH. I have no idea in the world what this is. Can any of you guys help me?
