well here is my problem If it rains out my car starts up and runs fine but if i drive the car on the street with it raining it backfires sputters and will die. it does not what to start back up but it will. last year i but a aftermarket intake on my brother thinks water is geting in the intake but i think its something else. any help is great.

 

are your plug wires or dizzy geting wet? I use to have a s10 that the previous owner cut a small area out of the wheel well to get the spark plugs out (if anyone has changed the plugs on a 91 s10 4.3 you probably understand) and when it would come a good rain the wires would get wet and do what you are describing. just a thought.

 

What you're describing is typically some electrical component getting wet and arcing.
