i have a 98 GMC 1500 series pick-up and have replaced all fuel injectors, coil pack,spark plugs, wires, distributor, ignition control module and it the diagnostics keeps saying there is a misfire in cylinder 2, also all O2 sensors, cataylic converter has all been replaced. Can't seem to figure out what else to do to make it run good. Anyone have any advice?
