Pinging 2002 150 4.2L I have a 2002 150 4.2 with 108000 Miles. It developed a pinging problem aroud 100000 Miles. The ping starts as soon as vehicle reaches operating temperature and remains consistant. I have tried everything imaginable.
-different brands of gas
-higher octane gas(makes it worse)
-complete tune up
-tested by my mechanic (4 days in shop)
-tested by local Ford dealer,another four days in shop. Ran 3 different computer programs and nothing shows up
-Contacted Ford Corperation..what a waste of time that was!
-Ran "Sea Foam" through intake,helped with acceleration but still pings!
Other than the pinging problem the truck runs great and has served me well. Any help would be greatly appreciated! |
