1999 Chevrolet Tahoe 5.7L Misfire, MIL Lamp on
Posted to GM Driveability on 6/17/2005 15 Replies

this truck came in with a p0300 and miss. I have to drive to a big hill a few miles away to get this truck to miss. lots of wide open throttle up a mile of steep grade, then back out til the tcc locks up. originally #6 would miss steadily for about 200 counts....
