[W126 Coupe] problem when raining

[Mister McGoo]

Kelly;A couple of details...... when your car "would not go faster than 20 miles an hour" is it on account that the engine splutters or will the accelerator simply not make it rev any higher?
Reading what you said, the heavy rain may be a red herring and has nothing to do with it.  One possible cause is you took on water from the gas station (condensation in their tank?  cover leak?) and you're sucking water into the fuel distributor. Water does not easily pass the injector system and kind of collects there until you stop.  (You may have sloshed up the water again when you made the U-turn).  Try buying a quart of methyl hydrate (also "methyl alcohol", "wood alcohol"... at the paint dept at Home Depot for example) and put half a cup (or more... it burns well, no damage possible!) into the tank.  That would get rid of the water... almost instantly.  I'd try that first.  Methyl Hydrate is cheap. -Bellamy
