please help!
I HAVE A 1992 190E 2.3L. I HAVE CHANGED CAP,ROTOR,WIRES,PLUGS,AIR FILTER,AND DONE OIL CHANGE. MOTOR IDLES SMOOTHLY, BUT WHEN ACCELERATOR STEPPED ON HEAVILY, IT RUNS ROUGH AND SERIOUSLY LACKS POWER. WHEN YOU LET OFF OF THE GAS PEDAL SLOWLY DURING ACCEL, MOTOR SMOOTHS OUT.


ANY INPUT WOULD BE APPRECIATED.
