2003 silverado 5.3 83000 miles , has a miss , code shows #3 missfire , changed coil , still a miss , swapped plug and wires from another cyl , still missing , not sure if miss switched over , probly due for a little tlc since plugs and wires are original, plugs and wires dont look too bad
what say the general diyers out there ?
