Question about 1994 Mercedes-Benz C-Class
My 94 c220 jerks while i drive. it is as if it doesnt want to change gears. whenever i drive at a constant speed the car jerks and sputters as if it wants to die out. whenever i come to a stop the car dies almost instantly. also the car wont idle when parked or stopped at a light.
Have engine wiring harness checked as 1993-1995 MB's were forced by US to use biodegradanle insulation on its wires. If thats not it replace coils and do a tunes up.

Throttle Body Cleaning on vehicles without electronic throttle control (most 2003 and down)
You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.
