RAIN makes truck studder....??

[bigstrokin21]

did an engine swap a while back after i lifted the heads on my old motor from too much boost and now im running a completely stock engine out of a early 99 like i had already. engine runs perfect and doesnt miss a beat ever. but when it rains and the roads are wet every once in a while it will studder. almost like u turned the key off for a half second. sometimes accelorating. sometimes stopped. sometimes just cruising so i know it just happens randomly. almost like theres a sensor getting damp. the crank angle sensor seems to be sealed well at the connection so im dumbfounded. has anyone else experienced this problem??? o and btw when its idleing and this happens it kills the engine. but if ur driving it stays running cuz its just a split second cut out

Mine was doing the same thing. If I had the wipers on intermittent, sometimes, as soon as they kicked on, my truck would do the same thing. I changed the cps and it hasn't done it again. Have you noticed that it only does it when the wipers start to swipe

hahaha actually now that i think about it i think so? thats weird. i have a cpl other sensors on other motors laying around. i guess ill just swap it and see

I'm guessing that if the cps is going bad, the wipers kicking on is enough of a jolt to the electrical system to make it act goofy
