I have a P0300 and P0302 error codes. This happened from getting the van stuck.

What is your question?

This just happened last week. The van is a 2012 model but, new with only 1000 miles on it. It is not used any more. I believe I fouled the #2 spark plug from rocking the van back and forth to get it unstuck from the snow. I can clear the error codes with an Autel but, they keep returning. The Autel gives me this reading: P0302 $07E8 and Cylinder 2 Misfire. The P0300 just showed up also.

What makes this problem better or worse?

Resetting the PCM smooths out the engine

How long has your 2012 GMC Savana 2500 had this problem?

I just recently got this problem.
