Good Morning community,
I need some assistance troubleshooting an intermittent misfire on a 2014 honda civic si 115,000miles code P0301.
Misfire happens early in the cold start, changed spark plugs and swapped the cold pack, it takes about 2 weeks for the code to pop up after i clear it. Here’s a freeze frame for the pros.
Any help will be greatly appreciated.
