Just wait untill the code comes back on before u buy coils, the CEL doesn't trip immediatly. Pointless to buy coils when you can 100% identify them as the problem just wait.

I had a misfire on mine, no CEL came on or any codes showed. It was only noticeable at idle and the #1 plug kept fouling. I took a chance and bought one COP coil (Borg Warner brand) and that solved my problem.

I guess you only get a code/CEL if you have a more serious or constant misfire.
