Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** the engine is stalling on acceleration I would first have the mechanic perform a fuel pressure test and a fuel volume test. If one of the fuel pumps is failing it could give you this symptom. If the fuel pressure and volume is good I would inspect the ignition system. A bad cap and rotor or a bad coil could cause this problem. The only TPS on this car is the throttle valve switch mounted to the side of the throttle body. This switch will not cause the problem you are having. There is also an air flow sensor potentiometer mounted to the side of the air flow meter. The potentiometer could cause the problem if it is bad.
Let me know if you have any questions.
The air flow sensor plate is strictly controlled by engine vacuum, there is no electronic control. If the plate did not deflect downwards on hard acceleration it is most likely due to the fact that the engine was stalling at the time. The throttle valve switch mounted to the side of the throttle body (down in the V of the motor) will not cause this problem. He needs to look elsewhere for the problem. I'd check for a bad coil, cap, rotor or ignition module. It sounds like you may be losing ignition high voltage on hard acceleration. Either that or there is a fuel pressure problem that he is missing. A restricted exhaust system would also cause the air flow sensor plate not to deflect downwards.
