P0300 but no check engine light
Today I took my truck to Advance Auto so I could have the kid there scan its codes for me and reveal what's wrong with my ABS. The short answer is, everything, but that's a topic for another thread (or possibly several threads). The thing that really scared me was his scanner also showed I was getting a p0300 code, indicating a random misfire. I haven't noticed any misfiring, and like the subject says, the check engine light hasn't come on. My own scanner shows no codes, which confuses me.
This truck has not run better in the entire time I've owned it, due to recently unclogging my cat and fixing some other performance issues. How do I determine if this p0300 is really an issue? My next move was going to be replacing the distributor cap, as I have already swapped on a different ICM. Truck has new plugs and wires. Is there anything else I should be looking into?
Don't you hate when that happens?
