Re: problem with 2000 ford ranger v6 4.0
What's the name of the part that regulates EGR? Because that's what it sounds like. Too much exaust gas being sent to the intake, causing it to lean and fouling the plugs after a short while.
It'd be like a hidden vacuum leak as well. Not a leak to the outside but an unaccounted for "false air" leak just the same.
