Replace it as I suspect it could be arcing to ground. I am dealing with a 300 and a 301 right now and I have a leaky valve cover gasket. You won't get much help in this forum. It's mostly younger people talking about big wheels and stupid crazy stuff they do to these cars. No one here could even tell me where cylinder 1 (it's the one closest to the rad by the way in case you didn't know) and that there is one coli pack per 2 cylinders. Try some other forums as there are many.

Did you have a misfirecodes before you replaced the plugs and wire? If not, then go back and recheck all your work..

No the problem was due to the broken ignition coil and when we tightened the throttle body back on we pinched a wire in between throttle body and gasket all fixed now!
