I drive a 1991 190e 2.3 with 130k mileage. The car is has been a great investment thus far, with only a few minor repairs, most electrical, that were simple to fix once the problem was isolated.

Recently, though, I have experienced a major problem:

Some mornings, I start the car and head off to work and I have problems accelerating. I step on the gas peddle, and the car spits and sputters, stands still for a few seconds, then lunges forward. Sometimes, I step on the gas peddle, and it will stand completely still and just spits and sputters. Once, it even stalled. On all instances of this occuring, it has been a particularly damp morning, with rain all through the previous evening + I would have not driven the car much beforehand (1-2 day lapse).

The first time it happened, I thought it was from moisture in my gas tank, so I put a can of dry gas in the tank. But, this didn't prevent it a 2nd and 3rd time. Later, I thought maybe it was from moisture under the hood. I have all new spark plugs and a new air filter, but a friend suggested it may be loose or faulty spark plug wires. Anyone on this forum have a suggestion???

PLEASE HELP!

Poor running

If is is only when its been raining, it is quite likely the distributor cap. Take it off and look for signs of a green staining on the inside caused by condensation.
