300E misses and hestiates after a Car Wash!!!
Hello Board,
My 1987 300E has a weird problem. After a car wash, it misses at idle, and when I press the gas it hesitates badly. This problem will go on for about 30-45 minutes after the car has been washed. After that, I guess the water dries out. I suspect that some water is getting where it should not be going. When I wash my car I am careful to not even spray too much water on the hood,because this ALWAYS happens and somehow the car still misses and hesitates after a wash. Any suspected places that water could go and cause this to happen to my car???

No expertise at all, but just to clarify for others: This happens after you wash the car yourself, right?
One suggestion: I know with the Meguiar's wash stuff I use, it's recommended that one not spray at all, but simply run an ordinary non-nozzle stream from the hose to rinse, as the gentle flow works with the chemistry of the wash solution to enhance a sheeting action and minimize water spots. Try losing the nozzle for a wash and see if not spraying water at all, but simply running it over the car as needed, makes any difference.

Overload protection relay
It's a relay behind the battery - you need to remove the plastic shield just behind the battery to get to it. It has a fuse on top, and I'm not sure of it's function, but it does tend to react to car washes. Keep a spare one handy just in case.

Sounds like your getting the distributor wet....but I'm not sure why if you careful not to get water in there. Make sure the bolts are tight. Let us know how it turns out Mike.

Check behind the battery area...
for water. The OVP and the fule pump relay, among other things, are there. They can give you those symptoms...
Unless you also wash the engine when you wash the car, then that is a different problem.
