Are there any DTC's in your system currently? If so you will need to address them. Also, is your fuel injection system adjusted to MB specification? Is the ignition timing correct? Is the vacuum line connected to the EZL control unit? What about your engine temperature? Are you able to get it below 90c? Lowering the engine temperautre will help once all the other factors have at least been double checked.

IMHO: H9DCO (good choice), fuel control set between 40% and 50%, and +/- <10% differential idle vs. high speed (2500rpm)
