Question about Mercedes-Benz E-Class
If you are mechanically inclined, recommend you begin checking fuel pressure. If you have an external fuel filter, may want to also replace this component.
If your fuel pressure is good, then you may want to check air intake. Have you done a complete tune up to your vehicle ? Have you checked for any codes in your engine control module ?

Dear FixYa Team,
I have the injectors clean up and replace fuel filter, but still it did not work. I think it's the intake valve is sticky, when I remove the injectors there were carbon inside the intake. Whenever I pump the accelerator intake start to back fire, after a few pump on it, engine gets better until it warm up then I can run the car with out that problem. Is it neccesary to correct this problem? If not it cost me a lot of money. Anyway thanks for the the suggestion, my car runs better than before. Limyukok

Is the AC on? The compressor can take alot of power and make it lope. Engine mounts can make it shake. coils, cap, rotor and wires for tune up at a minimum. EZL if you can find one cheap. MAF also can cause issue. If it is a 1991-1995 check the engine wiring harness as they get brittle and degrade.

By having it scanned and cleared with an OBD tool. This light comes on when it detects a problem. Could be a bad gas cap, or it could be a misfiring engine. The code you get from having it scanned will pinpoint the trouble area

Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.
