I've been misfiring. I was hoping someone might have had the same symptoms and might be able to tell me hat it is before I start buying coil packs and injectors and hope hey work.

-most of the time only misfires when I put it on map 1 on jb4
-misfires on cylinders 4 &5

might be spark plugs ? anyone wanna give it a shot? thanks!!!!
