CEL flashed last night, dealer no help
I have a 2010 Jeep Grand Cherokee with 80k miles on it.
So, my check engine light came on a few days ago and I assumed it was the common gascap/emission leak error. I went to Autozone yesterday during lunch and they read the code and confirmed as much.
Then last night driving home in dense, stop-and-go traffic for about an hour, the CEL started flashing, of course freaking me out. My jeep idled rough and accelerated sluggishly for my last mile home.
So, this morning I wake up and the CEL isn't on at all, but I still take it to the dealership. They pull their own code, but again the only thing thing they get is a gascap/emission error.
They really didn't have any recommendation besides replacing the ESIM switch, but they conceded that they didn't believe that is what caused the problem.
I replaced my spark plugs 1 year ago and again their was not a code indicating a misfire.
Any suggestions on what to do from here?
Also, still no CEL light driving to the dealership or from the dealership to work.
