Hi all -
Apparently my wife has been driving the truck ('99 F150 4.6L, 115K) with engine codes and the thing hesitating without telling me. I got in this past weekend and I can't hardly touch the pedal to get it up to speed without is missing and sputtering under ANY load. I limped down to AutoZone to get the code(s) read. Got three codes: 1st was a P0303, the others were a lean fuel mix and the an 02 sensor after the cat (I'm at work and forgot the exact codes for the other two at home, but I remember what they were about) The replaced the plugs about 6K ago and the wires about 10K ago. Used all motorcraft plugs and wires. My guess was that one of the coil packs was going so I replaced the passenger side coil pack last night but it didn't fix the problem. Is the coil pack for the #3 cyl on the passenger or driver side? If it is the passenger side, does anyone have any other ideas for me to move onto? It's running really bad. I have no idea how long it's been running like this. She thought it was just bad gas...
Thanks,
IYM
