I have a 2010 ram 1500 5.7. When the temp is in the teens and 20's the truck will not start, the check engine light comes on with a P0300 code, misfire. I take the neg cable off the battery to reset the pcm, then hook the cable back up and it starts up fine, no codes. It runs great like nothing was wrong. And starts everytime after that. It only happens when it freezing.
Anyone know whats going on. Thank you
