Thread: still mifiring..

Icm is good. Coils are good. took off boots from wires. Running premium fuel drove it all morning also used some injector cleaner and octane booster. Still nothing. Checked compression thats good. I was sure that something would have worked! Any other suggestions?

I had the same problem, at first i too was using regular gas and i kept getting a random misfire code and cylinder 3 sometimes. But i started using the 93 gas i had the code come on once, then i filled it up again and so far no codes came on. maybe it will take a tank or 2 for it to stop.
