Code P0301......

[Rinn69]

About a month ago, I had an issue that exhibited the exact same traits as the issue I had about 20 min ago. It will drive fine until you get above 3500-4000 rpm's, then it bucks and stutters. The CEL came on, but after I coasted/babied it to a parking lot, it went away. Got home and checked it with my OBD2-MX and it was P0301. Last time when I took it to the dealer, they said it was a cracked sparkplug, but I forgot to ask what the code was. I will check when I bring it in.....again.

I found the thread that @SILK posted back in Oct 2020 and will ask if they could check the coil pack too.

Best of luck mate. FWIW, I haven’t had any issues since the coil was replaced.
