91 300e problems because of the rain?

[mbzr4ever]

Don't laugh, this is what my mercedes mechanic told me.

OK, so the 300e ran perfectly about 4 days ago. Then I decided to use the 240D for a few days, and the 300e sat. Meanwhile it has rained a lot.

Yesterday, I took the 300e to run some errands. Everything normal for about the first 5 miles. Then, at a stop light it started to stall out. Sounded like it wasn't getting fuel, stumbling. Gave it some gas in neutral to keep it from stalling out. Made it to the post office, where I shut off the engine. Came back out a few minutes later, would not start. It cranked, but would not turn over. Tried a number of times, then thought I'd better quit, might run the battery down.

So I decide to walk to the gym ( few blocks away), do my exercises, then see if it starts later. And, of course, it is still raining. Who do I see on my way over? My Mercedes mechanic, he was passing by. Asked me why I was walking, I told him about the car that was stuck at the post office. He said, maybe something is wet, to call AAA, then drove off. Yup, that was the help I got.

After a hour and a half at the gym, I walk back to the post office, and started the car. No problem. Drove the car straight home. Looked under the hood, and the only thing I noticed was a hose that connects from the air filter to the top of where the cylinders are (don't know the name) was slightly disconnected from the hose rotting.

Could this have caused the problem? I had this (if not a similar problem) a few years back, and it was because the distributor cap was loose. Don't know the exact details, have to find the receipt. But I don't even know where to find the distibutor, could someone point out where it might be?

And I thought of pouring some SEA FOAM down the carburetor, took the air filter off, no carburetor. Just a flap that, when pushed, the engine died. HELP, need some guidance here...

Could it be from the rain, and something electrical be getting wet? If that is the case, mercedes makes one heck of a (BLEEP) car, and I find that very hard to believe! (This coming from a diesel believer).
