I have a 2003 Ram 1500 4X4 SLT 4.7 and every time it rains my truck will stall and buck along with a rough idle. What could be causing this?

Asked by May 10, 2014 at 06:38 PM about the 2003 Dodge Ram 1500 SLT 4WD Quad Cab SB

Question type: Maintenance & Repair

It will only idle rough and stall/buck/jerk when it rains, or more precisely (when it is a
humid rainy day) if that makes sense. After a couple of days the check engine light will go
off and the truck will run fine. However from time to time my truck idles a little rough but
nothing like when it rains, there's no bucking or jerking. Anyone every have this sort of
problem.

Next time it happens open the hood in the dark of night and look for spark jump. (No light what so ever shining on engine) Look around the plug wires, coil and distr cap. I feel that you will see lots of blue sparks jumping from the wires. Kind of pretty but it will run like crap. Lol. Might see a little of it when the humidity is low and not raining but when humidity is up or it's raining it will jump spark like crazy. If you see it replace the items it's jumping from( plug wires, dist cap, coil, ect)
