wtf???????? few weeks ago, our navigator started running like it had a weak or dead cylinder, then it fixed itself. little while later it started doing it again, then the sevice engine light came on. pete had autojoke scan it, said #2 misifre, so last night i changed it, didnt fix it. last week the truck had what i thought was a lifter tick, a low oil sound, but that went away too, well i was getting pissed so i pulled the coil cover off the pass side valve cover. if you havent worked on a 5.4 dohc in a navigator do not try it. holy :q:q:q:q what an engineering marvel. so, i got the coil cover off and instantly i see what appears to be 3/4's of a coil boot on top of the coil, wtf? i pull the #4 cylinder coil out and omfg lolololololol this is what was waiting for me inside the hole.
so i went and grabbed a new plug, luckily the plug failed , but the threads didnt rip out of the head, the bottom of the plug was still threaded in. i put a new plug in and new coil and the truck is running way better, but it still has a sputter, i'm thinking i should have checked all 4 coils on that side, i think it might have another dead coil, it does have 218k on it and all the coils were original. what a piece this truck is, i hate the thing.
all this happened after we spent about 260 bucks and allllllllllllllllllllllllll day yesterday chaning the idler arm, both lower ball joints and upper control arms, the whole front end was ready to drop out of it!
