Hi All! I have a 96 A/T V-6 that I have owned for only about 6months. Shortly after buying it I noticed it was misfiring at warm idle and the check engine
light came on. I had it checked at Autozone and it showed #2 cylinder misfire. I replaced the coil, plugs and wires and added some prem gas and a bottle of lucas to clean out the system. Code cleared, misfire stopped!
So over the last few months, anytime I got down to about 1/4 of a tank of gas and romped on it to pass someone, it would start misfiring at idle again. I added more cleaner and prem. gas, checked plugs and wires and then it would clear up on its own.
Since it did this several times, I figured it had to be the fuel filter and maybe some crud was getting kicked up, so I have now replaced that as well. As of last week the misfiring is back and now the previous "fixes" aren't working to clear it up. I bought a new injector but I really am hoping it doesn't come to that (taking the fuel rail off is not something I want to do). I haven't checked the compression yet but it seems to be ok.
The misfire is only at warm idle; it smooths out when I am driving. The plugs are gapped correctly, there doesn't seem to be any arcing... Any suggestions would be sooooo appreciated!!
