2003 Dodge Ram 2500 Sport, runs like crap, did have a code but dont remember it....said something about "multi-cylinder misfire" or something like that....removed all 8 plugs, and 2 of the 8 were actually almost red on the end, I've seen ALOT of spark plugs, but never any colored like this. Removed and replaced all 8 plugs, check engine light went out, and truck ran fine. Returned truck to mother in law, and last night said it was at it again, but much worse....thought it was gonna quit on her.....I took said plugs to Autozone, and asked what would cause such a peculiar color on the plugs, and an unanimous "Fuel Filter" answer was immediately given. What do you guys think? Is he full of mud, or speaking the truth? Would appreciate any advice from anyone....Killer forum btw!!!!
