I have an '87 Ranger with a 2.9 L V6, and it has a problem. One of the
cylinders is eating spark plugs. The engine will start, but it runs really
rough. So rough, that the whole truck shakes. When I took the plug out of
the hole, it smelled a whole lot like gas, more so than the others. The
center electrode is scuffed up pretty bad, and the side electrode is burned
halfway back to the plug. Anybody have an idea why the plug would burn up in
that one cylinder?
my GUESS is you have a fouled injector and it's running lean on that
yeah.. you smelled gas but that's after the fact, when the plug was no longer
firing the mix... pull the new plug after a few miles and see if it isnt snow
pull all the injectors and take them to NAPA, have them cleaned and flow
tested... or just replace with some from a wreck.
check fuel pressure or replace FPR and do fuel filter change too.. and dont
buy gas at low volume stations
