Just changed the oil and fuel filter in the rig and decided to pull the plugs, only did passenger side though. Came across something very interesting so I figured someone here could lend their expertise. These pics are of the same plug, but only one side seems to be getting fouled. I believe these are the #4 plugs(center on the passenger side). Sorry to sound stupid but am drawing a blank right now on which side is which. :lol:
The rest of the plugs on the passenger side are fine, they all look like the clean side of this one. I have run about 6 tanks of gas with 92 octane since complete tune-up. Only had "spirited" driving on about 3 tanks though.
Not very good a reading plugs so I figured you guys would know what might be causing this more than me.
Thanks
