- 2002 explorer limited v8
Hi,
I have a misfire on my 02 limited explorer. It runs ok when cold, but once it warms up, it has a rough idle, and misfires under light load in lower rpms. At WOT, the engine surges and the HP curve is not smooth at all.
I've ran fuel injector cleaner twice, changed the plugs, and changed the COP's. As a result of my efforts, the trouble codes indicate that after each attempt to fix it, a different cylinder goes bad. Right now it says that cyl 1,2, and 8 are misfiring.
Any Ideas? It seems odd that the problem would move, and correct me if I'm wrong, but those cylinders are on different banks, so its probably not an O2 sensor? Is the car sensitive to the type of COP's? I replaced all with Granetelli's from summit racing.
The truck is all stock except for a CAI from my '00 mustang. It also has the Mustang Mass air sensor, but its run fine for over a year.
Help please!
