A month into my '10 Ranger 4.0 with 135K miles, runs great - some rough idling. Some chain slap at startup. Now OBD lights up - Code indicates #4 misfire. I reset OBD and it reappears. Tried to pull #4 plug and get a view, but its so very tight. With solid but careful force with my 18" breaker, I get maybe 1/8 turn out of it and a sudden hard stop. I tried to slightly re-tighten, but it's not budging either way. Investigating the web, a UT video indicates this is common, suggest spray and soak 1-2 days with combo of PB Blaster and Brake cleaner solution. I've done that and waiting but really uneasy about snapping the plug and a cyl. head redo. Drivers side so possible, but even with that it looks scary for this old school shade tree guy. While waiting, I'm shopping replace/rebuild options just in case. The plug in there does not look original (no red paint tip) and the Oil Filter I replaced was apparently put on by a gorilla and think this engine likely has been abused by a neanderthal. PLEASE any hope or advice?
Greatly appreciated!!
