I did get the new gas cap already and it worked for a few days, but then CEL came on again, same one and only code. I am testing a theory right now but I believe that the CEL is only coming on for me when my fuel tank level is about half or lower. Does that help anyone narrow down what it could be? I am going to just not let my car get below a half tank for the next 2-3 weeks and see if I can keep this CEL at bay. If it doesn't come on I will be pretty confident in relating it to fuel level. Engine load level, boost level, ambient temp and humidity, none of this seems to play into whether it comes on or not. I have intentionally subjected the vehicle to various load and climate conditions and the CEL hasn't come on above half tank. Below half tank, just cruising in 6th gear on the highway and boom CEL on and cruise flashing.
