Todays cold start yielded a single cylinder misfire, definetly not two or three. I let it idle and it cleared up and ran smoothly in less than a minute and was fine for my entire commute. It did not trip the SES light. After swapping 1+3 coils yesterday, this tells me it was probably cylinder 1 that misfired. I will pull the codes at lunch and see if I have a pending code for the misfire. If no pending code, I'm not sure what I'll do.
Suggestions welcomed.
