This may be a bit vague but the last 3x I went to the track I got an engine misfire code (CEL)after my 2nd session I believe. I always put in 93 octane fuel, and only name brand fuel.
Each time I top off a few miles from the track. I thought maybe the station I did that at was the problem, so this time I went to a different station before going to the track. I got the same code again, only this time I also got codes for (and I am paraphrasing because I didn’t write them down) loss of communication with PCM and loss of communication with the steering column.
I know that you can get weird codes if the battery is bad. I have not replaced the battery since I got the car in 2016, and for all I know it still has the original battery.
The car starts right up and is kept on a trickle charger all winter.
I did notice today (after washing her and polishing)that she started up but ran rough when I gave it throttle while parked for maybe a minute. Not sure if this is related but it never happened before. No new codes are displayed.
Anyone have any thoughts or suggestions?
Thanks!
