AFM/DOD Q&A

2013 GMC Sierra 1500. Currently at the dealership:

SCAN AND FOUND P0304. CHECK AND FOUND IGNITION COIL FIRING. CHECK AND FOUND NO COMPRESSION ON #4. REMOVED VALVE COVER AND FOUND BENT INTAKE PUSH ROD. RECOMMEND ENGINE TEAR DOWN AND INSPECTION FOR LIFTER/CAMSHAFT DAMAGE. $800

Unfortunately, misfire happened on the way to work, so it's probably done 50 miles since it started misfiring.

So I'm going to take it home 5 miles and try the lifter release method. Perhaps AFM delete if it comes to that.

Would it be better to drive it the 5 miles with:

• New pushrod

• Bent pushrod

• Removed pushrod?

Thanks,

Bob
