I just got back from the car wash,, barely.. Anyway I washed it with the high pressure washer, top and underside. when I backed out it stalled out. After I tried to start it, it would Idle but as soon as you hit the throttle it would stall out, idle was rough, almost like it was dieseling. Let it sit for a bit idling then tried to drive home, it was like it was getting fuel off and on, I was driving down the road and it was accelerate, die accelerate die all the was home, getting to a top speed of 20, I could just barely touch the gas or it stall out. Has anybody else had this problem, and what do i do to solve it.

 

Are you saying you rinsed the motor off? If so you have COPS that are wet and probaly fried now and therefore the truck is misfiring bad. Is the check engine light on? I did the same stupid mistake a while back and had 2 cops that fried.

 

I agree, sounds like some water migrated up into your coil packs. you could try taking each individual coil pack/ spark plug wire and drive the moisture out with wd-40. And like King Ranch said, hopefully you didnt fry them.

 

Looking at where he lives if he washed the frame down could have got water into the now famous corroded and cracked fuel control module. They are starting to show up very frequently now, just a thought.

 

could be an ignition coil if you soaked that area by mistake or something, running on one less cylinder

 

Your engine isn't designed to get wet.

The COPS are not sealed good. Causing a serious misfire condition, which could harm your engine.

If you had a regular engine with plug wires and a EDIS, you would be fine.

COP engines don't like water.

I know this from past experience.

 

I did not rinse the motor, nor did I lift the hood, after it stalled the first time i checked under the hood to see if it was wet, and there was not allot of wet under there just around the bottom of the wheel wells, but but no thing was soaked by no means. But I did spend a lot of time on the under side, frame rails and under box.

I just went for a drive and it is allot better, but still has a bad miss, if I ease on the gas it will run fine, if i push on it it starts to cut out, to me it is like the fuel is not going through. And i have no check engine or any dash lights on.

 

This is the likely culprit. Which would explain why, as it dries out, it's starting to run better.

 

So will it dry out and work properly, is there a way to seal it, move it to a better spot? I read up on the FCM, I see others have had problems, but they all say it just quits.
Guess I will see in the AM, hope its better.

 

It's possible that just the casing has cracked on yours and the internals haven't been damaged yet. When the water went into the crack it shorted out the circuit board inside.

 

mine quit going into an auto car wash when the chassis bath hit it when it was 6 months old, had to push it out, started after a few attempts, been fine since

 

Its is back to normal today, no problems.

 

Lucky...

 

Be on the safe side and lower the spare tire and check that module..I have seen a thread on here somewhere that it took out the fuel pump and the PCM when it shorted out. You just may have got lucky if that is the culprit.

 

Going to check it out tomorrow, maybe coat it in silicone or something.
