P0302 Engine Code
So, started up my ride yesterday and got the check engine light. Pulled the code and it looks like the P0302 2nd cylinder misfire. So, mechanics out there, I run Chevron premium all the time. I had the plugs changed about 10,000 miles ago and I am pretty sure the wires at the same time. What else should I look at doing? I know that it could be several other things, but I am wondering what I should trouble shoot first based on the fact that I already run awesome gas.
Thanks in advance for any input.
