The 4th cylinder is missfiring in my truck. When I first driive the truck it runs fine for the first couple of miles, then it starts to missfire. I have tested both coil packs, replaced all plugs and wires, and run fuel system cleaner regularly. Sometime it will be missing the starts running great again. Some times it idles fine other times it dosenot. Any sugestions?
have the same problem?
