I recently got a used 2009 gti, it has about 100k miles and 2 days ago it started misfiring when I press the throttle to a certain point. The first time it happened the EPC light came on and my CEL started flashing. I haven’t seen the EPC light since turning my car off, but the CEL won’t go away. I went to autozone and used their obd2 scanner and it gave me the P0301 code for the cylinder 1 misfire. I’ve changed out all the spark plugs and the coils aren’t the issue, but every time I check the obd scanner the same code pops up and I don’t know where the problem lies. If someone could help that’d mean a lot!
