My cylinder 4 plug keeps fouling in has gone out 3 times the last 4 months...that's the only one i have the 5.9 and the shop i took it to to see why did a bunch of test (for free) and couldn't tell me. they said it could be an internal engine problem or a leak in my intake manifold anyone have an issue you like this or an idea of what could it be the code reader says it was a "Fuel Foul" on the plug.

Thanks.


P.S. anyone ever used Remington mud brutes or know anything about them or another mildly inexpensive mud tire (35) with descent tread life

 

i dunno why your plug keeps foweling

but for tires check out procomp there relitavley cheep look at the xtream A/T's as well i have them (35') and really like them they are agressive like a mud tire but harder rubber so theyll last longer and im guessing since you have a 2wd its mostley for looks anyways

 

Possibly an over-rich operating (or faulty spray pattern) fuel injector. It may be staying on too long or dribbling instead of spraying.
