Amateur mechanic (myself) replaced head gaskets on this engine after coolant had leaked into cylinder and burned. Repair went by the book. However, cylinder now one misfires and spark plug looks wet (clear) and sooty. All cylinders all have good and equal compression (145 p.S.I), new spark plugs and wires were installed, coil packs register equal ohms, intake manifold was removed and installed three times carefully, cleaned and tightened to spec, new gaskets installed. Misfires still in cylinder one. I disassembled the fuel rail and injectors, cleaning each one forward and back with a twelve volt battery and brake cleaner. Reinstalled injectors on rail in a different order before replacing in van. No change. No visible exhaust burning. Vacuum leak? Next steps? Possible solution?
have the same problem?
