Just about everytime it rains while my truck is in the driveway, i get a misfire the next morning. Well id describe it as more of a studder that goes away after a mile or 2 of taking it easy. no CEL and only when i get into the throttle moderately. sometime its worse, others its not so bad.

I think it might be water getting somewhere it isnt supposed to, but and help or advice is greatly appreciated!

Is the seal between the rear of the hood and cowl missing or loose?
If so, I have heard of cases where water would drip on the dist. cap and cause this.

 

my dads old 96 ram did the samething...we traced it to the 02 sensor gettng wet, for it popped a CEL once....got the codes read, and about an hour later the CEL would always shut off....and it was the 02

 

My 2000 Ram 1500 had bad rubber at the back of the hood and did that too, untill i glued it back on.
