I've been drivivg trucks for years on the job but never owned one. I've
just purchased a 2003 Ram 1500 4x4 & LOVE IT. It's a pleasure to drive!
One Problem though. Check Engine Light comes on after getting gas.
Still has some factory warrenty left but I'm getting tired of taking it
back to the dealer to get light turned off. Remove battery cable &
light goes out & everything's fine until the next time I get gas! I
think rubber seal on the gas cap is a bet weathered. I've applied a bit
of grease to the seal as this should soften the rubber a bit and help
it seal. Also, when the gas cap is tightened, I apply downward pressure
to it, this enables it to be tighten a little more....
