Error code p0301 and sometimes p0300
I have a 2014 Z28 with only 3,000 miles on it. About 6 months ago it gave me and error code of P0306. I replaced the sparkplug coil and that seemed to clear the issue. Now I am getting the same code for cylinder 1 (P0301). I did the same thing and the code will not go away, now sometimes code P0300 is coming up. The general engine misfire code. Anything else I should check?
TIA |

Either start moving parts (injectors, coils, plugs, etc) around and see if it follows. Or get a scanner that is recording/showing live data and dig into what is going on to cause a general misfire.
With something as few miles as that has, you might have fuel issues or chewed on wires, depending on where it is stored. All of this is assuming that I, a lowly SS owner can comment on a Z28. Still trying to figure that part out. |

I agree with above, likely wiring issue but you are going to need a good scan tool with logging capabilities to diagnose without guessing.
Do you know anyone with HP Tuners, would be a good start.

HPT Tuners would help, but I'm not aware of anything else below about $1000 that will do what you need. Something that will display misfire counters real time.
