2016 Suburban P0300 Random Multiple Cylinder Misfire Detected. 66,900 miles

 

Took to the dealer. The Check Engine light and Stabilitrac light. Rough idle and slow acceleration. I thought oh no my second lifter failed in this vehicle.

 

Dealer said it was coils/plugs and wires. I said I will fix it myself. Plugs  and wires were replaced at 55,000. I replaced the (8) coils with Delphi parts.

 

RESULTS: All codes gone. Runs like a new vehicle.
