Help with v10
 

My neighbor has excursion with the v10 and he has a misfire on 1 and 7 new plugs and injectors and filter anyone have any suggestions

Changed the coils?

^^^^^^ that's probably it. Get the set of ten off eBay. Wish I knew about them before I bought mine v

if the coils dont fix it (which it probably will) check the compression. also when you replace the coils clear the engine codes

I would say the best solution is find a boat owner and sell them a new ancor!

Is there a CEL? If a coil is bad it should throw a code and tell you what one.

Drove mine for two weeks with a bad coil the last time before the check engine light came on.
