2012 check engine light came on the other day stayed in for a couple of miles then went away. Couple days later when I started it I was in the driveway for a couple minutes and the light came on again. I pulled the code P0300 (which covers a lot).
I searched the other posts and most of what i’m finding are other factors (rough idle, misfire, etc.). Thing is it sounds and runs strong. I disconnected the battery to reset the code and see if it returned. Today it returned.
Now since i’m looking for something specific I “feel like I feel a slight tremble on acceleration and a slight stumble when I stop quickly. Neither were noticeable on the tach as it’s a flutter at best.
so my question is what should I look at first on the list of possibilities. I don’t want to just toss cash till I solve the mystery. Same token I don’t want to make a small problem worse.
Thanks for the info.
