Many of you will recall that I have an overfuelling issue with the c200 6 months ago. The following was replaced.

-OVP
-Plugs
-Engine Wiring Loom
-Engine Temp sensor
-Air temp sensor
-MAF
-O2 sensor tested out ok.
-Voltage drop to the ECU which was verified.
-Fuel pressure ok.
-Throttle actuator- replaced, but hums when key is on motor not runnig

When first started (hot or cold) when you step on the throttle to pull away for the first and 2nd times, the car will have a "lull", and if you put your foot down further, it will miss. In addition you can sense the ever slightest "hestitation" when at constant speed until the car heats up.

In addition i will get intermitant ABS lights.

Im also getting faults - 5 + 6 pulses from the main fuel computer. What are these?

Any ideas.
