2008 Chevrolet Express 3500 6.0L Poor Idle Quality, Hesitation, MIL Lamp on
Posted to GM Driveability on 2/4/2012 8 Replies

Compression is good on all cylinders. 152 - 155 i cleaned ignition coil grounds and seemed to work for approx. 2 weeks.

The vehicle runs fine no cut outs at cruise but stopped at a stop light it will stumble a little bit but not all the time.

Heres the freez...
