Good Afternoon team Ferrari: I had some pending codes in my car after cleaning the back of the engine that I cleared. None were related to the new codes that just showed up after the drive cycle. After clearing the codes I ran the car till if fully warmed up and no codes re-appeared so I turned off the batters and ran the car through the drive cycle. When I returned home there were new pending codes on the left bank: P0300 - random misfires P0301- Cylinder 1 major emissions there is no CLE and the car ran fine. Actually ran better than the last few days. Any advice would be welcome - I need to get the car through emission this month before storing the car for the winter. it seems I am chasing codes ever since replacing the thermostat and cleaning up after the mess. the car has not had a CLE light?
I see the 301 code as a misfire. If you haven't already changed out your COP's, it might be time. If you've recently done so, I suggest swapping cyl 1 with another one, probably on another bank just to be sure, and see if the problem moves. Image Unavailable, Please Login
That was fast! I have not changed the coils and the car has 38,000 miles looks like it's time to change them all just to be sure not I know a few have been changed. Thanks
