Hey,

This problem keeps getting worse and I was wondering if any experts here may know what could be wrong. The description might be sorta long, but it's necessary to describe what happens, it's really awkward.

Here is how it happens:

In the morning (or any time the car has been standing for 10 or so hours), I turn on the engine and leave my house. After about 3-5 minutes I drive down a hill, and when I get off the gas pedal the RPM needle JUMPS to 0. The same thing happens when i get off the gas as I'm nearing a stop sign or traffic light. If i don't touch the gas pedal again and just brake, the engine will die once the car slows down. Sometimes I can prevent that by changing to 3rd or 2nd gear or just accelarating to try to get higher rpms. If the engine dies, I have to wait a few minutes for it to start again (if i'm lucky).

More recently, the problem has gotten worse. In addition to the above, sometimes, when I come to a complete stop the engine does NOT die, but when I want to accelerate from the complete stop it DOES. Also, the engine would start again almost immediately, but when I put it back in to Drive (or 2nd/3rd gear for that matter), the same happens. The engine dies as I hit the gas pedal.

Overall the car is in a very good condition. I get it serviced regularly. I also brought my car to the shop several times now, but they can never find the problem.

Here is some more info on my car. It's a 1992 E300 automatic, 6 cylinder gasoline powered. It has around 122,000 miles.

Lastly, 20-30 minutes after cold starting, the problem tends to go away.

Anyway, thanks for reading this, and I would GREATLY appreciate if someone could lead me in the right direction. It's become increasingle dangerous driving my car as I could get stuck in the middle of an intersection at any time.

Thanks
