Upon closer examination after removing the coolant tank out of the way.... The rest of the spark plug is STILL down in the hole. Seems to be WELDED in solidly. No way have we been able to get it out... Trying WD40 last night (We had to stop. it started snowing, plus i had to go home) Although, WD40 needs time to penetrate, so i should think that sucker should be nice and lubed.
were gonna check the fuel filter today, if thats blocked then change it out. although, that leaves the issue of the plug still down in the head, welded in.
As for the O2 sensor.... Where is that located? Might as well take a look at that too
