Default Misfiring p0300-306 help quick!

Replaced spark plugs and spark plug wires used the OE plugs and wires everything hooked in correctly but I did crack an ignition coil to where the plastic broke off could this be the cause?

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.

Check to make sure u didn't pinch any wires while putting the throttle body back on I did that with my brand new wires replaced the one wire and it fixed the problem!

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!
