    cel light comes on when it rains

    ok so after searching for hours ive decided to just ask!! LOL!!!
    the cel light comes on when it rains. it will bog down, pick up and bog again, doesnt want to idle right and almost seems to back fire then the light will come on. It was raining last night when it did this, and this morning the cel light was off and the car runs fine. The last time it did this, the car ran like crap till the cel light came on then it ran fine, and the light went out after a few key cycles. I cant figure out whats wrong. the dealer says it sounds like moisture on the maf, but i took it out cleaned it and sealed it good when i put it back on. If you hook a code reader up it doesn pull a code. Whats wrong??

    MAF + moisture sounds about right.

    yep thats what everyone is saying. Its just weird that i can wash the engine bay and it wont do it, but it will do it when it rains. Oh and i have the spt short ram intake, not a cold air. I should have mentioned that. Im goin to replace the maf and see what happens.

    If your going to ask a technical question then post your mods.Basic common sense.My guess is you have an aftermarket intake yes?Probably a short ram?

    sounds like bad Coil on pulgs MAF its going to get water all the time but it only measures air and temp i dont thing water its going to stick around when you have air blowing though it, but my guess would be the COP shorting out on the water as it splash it, what you can do to test this is get a spray bottle and just start spraying your engin down and see if you can get it to do it again,
