Posted to GM Driveability on 10/18/2008 9 Replies

truck came in with numerous misfires. found injector leaking and in bad need for tune up. after t/up and injector replacement still have misfires on cyl 4 and cyl 3. Cyl 4 seem to be worst and predominate. They are not as bad as before and don't occur at idle....
