Angry Pcm Fried??

Ignition Coil Control Circuit 1-8 SES CODE thrown tonight.
PO351-PO359 were thrown tonight when normal driving. It had just rained hard as hell. Remember i live in florida and we get stupid hard rain. Car doesnt want to stay started, and will only idle till i tap the gas and it cuts off.

You think that there is a short somewhere thats causing the car to lose the tune, or that it maybe fried a coil or something?? Or is there a electronic control modual or something to that effect that controls all the coils.

Come on guys i know that this has to be someone that has even the slightest idea or something.

EDIT:
Ran the car a few minutes ago, and it idled ok, but my alternator is spiking every now and then on the volts its putting out. Also my fans are set to come on at a certain engine temp and they dont come on at all. And they are also set to stay on for 200 seconds after the car is off, and they dont even turn on let alone stay on after the car is off.



PLEASE PLEAE HELP!! This is my DD and im stuck at home and outta work.

Thanks

How about some plastic safe contact cleaner, and some dielectric grease in each connector?? Works for me.

Please do not clean with WD-40.

Go to the auto parts store and get electrical contact cleaner. Same price, easy to find, and is formulated to do THIS job.

Whatever floats your boat, but WD-40 works better IMO....Lubricates the O-ring and Displaces Water.

well This ended up costing me nothing in parts. Girlfriends dad is a tech, so he was going to look at the car for me. I drove it on a trailer 25 minuts from where it was currently. I guess the nice hot florida air dried up the water that beat the hell outta the car the previous week. So he goes to look at it with the scanner hooked up and finds NOTHING. At this point im stumnped and so was he. He drove it and said it ran great. So im now driving it and there is nothing wrong at all. Only thing that i can think of is that there was water in the connectors and the long drive dried it all up...... im so happy
