[W126 Coupe] problem when raining

[560secFL]

Hello all

Two days ago I allowed my 1988 SEC to get very low on gas so I went to the
gas station and put $40 worth of gas in just over a half a tank. I left the
gas station headed towards the grocery store half a mile away and about
halfway there my car would not go faster than 20 miles an hour when I
pressed on the accelerator it just bogged down. I got it home about 2 miles
away and put some dry gas in the tank and did not touch it until the next
morning, next morning started a right up and ran fine.  I drove to my office
and it seemed fine so I figured it must of been some dirt or something in
the bottom of the tank and had cleared itself up.  Later in the day I was
headed off to Stuart about 10 miles away and about two miles into my trip it
started to rain very hard so hard I can see so I decided to turn around.
just after I did a U-turn the car did the same thing as it did the day
before and would not go over 20 miles an hour which didn't matter because
you could really not go over 20 in the rain anyway made it back to my
office. I do remember the first time it happened going through puddles and
it was raining that day also My conclusion after this was that it's not a
fuel problem but a moisture problem getting into to or on something maybe
the ignition coil, or distributor Anyway if anyone has any suggestions I
would greatly appreciate it.


Thank you in advance
