cylinder 1 missfire help?
Well, i have a cilinder 1 missfire code, my wife had placed 91 oct on my car which is tuned for 93 oct, it was driven hard and according to bama it could be a spark plug that went bad or the coil, i replaced the spark plug and the code is still on, could it be i have to replace the coil as well? I dont want to just buy the coil which is 70$ and not solve the problem? Anyone else hd this issue in the past? The engine does kind of like a lagging sound.

I may be wrong but I think an injector is unlikely. Coils in my experience have a much higher failure rate. Technically you could do the same procedure though with swapping injectors.
