    You probably got some sensors wet and ruined them. My bet is on the MAF being bad.

    I've had a bad MAF sensor before actually changed it about two months ago and it didn't cause the engine ping. I've read that the knock sensor could cause a ping, do you know if any other sensors can cause this?

    All our sensors "should" be weather proof because of the seals.

    Please give us more information. Did it all of a sudden make the noise when you hit the motor with cold water? If so, that might be an exhaust leak. Although that shouldn't cause a stall.

    A bad bearing will often sound fine at cold start up when the oil is thicker/cool. As it thins and warms up, that's when you will have the symptoms.

    Do us a favor, get a vid of the sound. Hood up, car idling and up to temperature. Then give it a quick rev and let it fall back to idle a couple of times.
    I drink..so consider that when reading my posts.

    No it actually started the next day but I didnt drive the car after I cleaned it all up. I parked it and drove it the following day and thats when it started. Its a little upsetting because I just got my intake gasket changed and the radiator changed and just recently got it all painted too and now I'm having this problem after spending sooooo much money.
