Re: v10 ford
i work on them quite often, they have 2 common problems. 1 is the coils die and cause a misfire and if the computer doesnt tell you what cylinder it is and just gives a random misfire code its tedious to track down the culprit. 2nd is the threads in the head for the spark plugs are stripping out, aluminum heads+not many threads leads to trouble, there are some kits available to rethread them while still installed on the engine but i havent used them yet. they have platinum plugs so you shouldnt have to touch them for a long time.
