Running rough after raining
My trusty old Ram is starting to sputter after a rainy day. My guess it's probably the spark plug wires. Once she's running and warmed up, she's fine. On a dry day, she's fine. Never changed the wires, never complied with the TSB.
What do you think, wires? If so, recommendations? Don't need anything exotic but if I'm going to go through the trouble, I don't want junk. TIA. Todd

when its dark out crack your hood open and take a look inside and look to see if there is any bluish arcing coming from the wires. maybe even take a spray bottle andmist water over the wires to see if it affects the way it runs. msd makes some nice 8.5 mm wires and you shouldnt have any trouble with those arcing. while youre in there replace your cap and rotor because that could be causing your problem too. depending on the age and condition you might also want to change your coil.
a set of msd 8.5 's will probably run about $75

Thanks guys. It's gotta besome kind of moisture problem. Tried spraying with some water and sure enough it started running rough again. I will try to take a peek tonight but I think I will pull the cap, rotor and wires as they have never been changed in 77,000 miles. Dodge cap and rotor or after market?

I had the same problem on mine. I did the spray bottle at night and got quite a show, and even a little shocking experience when I tried to move the coil wire. I wound up having a couple of cracks in the coil wire and in the coil itself. Showed up real easy at night with a little water added to the mix.

Bought a set of MSD wires and got a cap, rotor and plugs from NAPA. Jeez Louise, what a PITA trying to get to the old cap and wires. Sure would be nice if the would have mounted the distributor in the front of the motor. Don't want to justyank everything off since it seems so sensitive on how you run the wires. Decided to put it off until I had more time and light. Thanks for the suggestions. BTW, do you still have to follow the TSB using the heavier MSD wires?
