2007 Ford Explorer 4.6l 3v Missing/Bad Coils

I did all 8 coils and new plugs at 105K miles on my 2v 4.6 V8. I didn't have any issues before hand, but I know the coils tend to die a slow death, and it was easier for me to replace them all at that time since I had them out, and for the 200 ish bucks it was worth it to me.

Hard to tell if your issue is plug/coil related, or something else.

FWIW, independent shops that do lots of business have gotten very efficient at doing the plugs on 3v mod engines.
