random and missing idle question

[aeveret2]

I have finished my 60k service, and now when I start the car it seems as if it's running on three cylinders. The engine has a noticable miss and when I pull the #2 injector plug; the running condition does not change - so I think it's a #2 missfire. I replaced the plugs and wires and I checked for spark, all those are good. I pulled the #2 plug and it is a little wet so I have to believe that I'm getting fuel. The injector resistance is correct and there is voltage at the injector connector. What have I missed? What other tests can I do? thanks for the help in advance.

Check the caps in the ECU. A leaky or burnt out capacitor can cause this.

checked the ecu and caps to-day and it is clean as a whistle. I believe the caps have already been replaced when the ecu was socketed. The car is still doing the same thing - it's running on three cylinders, and I can't seem to track it down yet. Anyone else want to take a stab at this?

Simply check for spark, if you dont know how search and you'll come up with many answers. IT could be your coil pack being burnt out
