Never have I ever.... (HELP)

[dvmotorsports]

I took the 318is to the wash today to get it cleaned up for the new owner. Well once the rinse cycle came on and a bunch of water went into the mesh area at the base of the windshield the car died. So I sat there for two hours until i could get it to start. Finally!

Here is the problem, it sputters unbelievably. Under accel, decel, steady, and at idle. Sometimes at idle it dies. I changed the plugs and wires. I also tested each plug pack (can't think of the real name). They operate between 0.4 - 0.8 ohms. Well they are all in range. And something was arcing under the fuel rail when the ignition was in the on position but not running.

Any ideas, suggestions? I am pretty sure it was water related. But now that the car is dry, it is still messed up.

well to be honest the minute you said power wash,, i thought uhoh.. ECU is soaked.. check your computer dude. it might have water in it

^^^ what he said. Caught me after having my 328is for only 4 hours...

Open it up, clean everything you can see (corrosion) with a small toothbrush and then reseal the ecu.

Also check if the soft cover that is in front of the computer is placed right, there is a small edge of iron you have to slide the cover in.
If it's torn, replace it.

The problem is caused by somewhere near the window, in the plastic cover. Dealer told me it's caused by the nut plugs that hold it.

I thought the ECU was in the passanger side floorboard? Am I mistaken? Oddly enough, the car ran fine this morning. So it had to be water. But what ECU are you talking about?

ECU behind the firewall int he passenger side of the engine bay. It's a common problem when peopel get their cars washed.
