Hello Mike,
I thought you found good ovp test procedures on mercedes shop .com?
A rough idle could be caused by the fuel to air mix...
Which I have read the test procedure for that using an oscilliscope[sp?]...
When it comes to adjusting the fuel mix and electronic controls, I would prefer finding a good dyno shop to dial it in with it on the dynometer...
They can adjust for most powerfull settings, or most fuel economy settings, or maybe somewhere happily in between those two extremes...
Just trying to be helpful, thanks.

I have a thread on mercedes shop
http://www.mercedesshop.com/shopforu...650#post684650
but its not yet much help. I think I may order a new OVP if I dont get a defintive answer they're not too expensive. The rough hot idle is wierd as it seems to have come on from nowhere. I disconnected the air-flow sensor Potentiometer to see if that might help then went for a 15 min spin but no better, though the car seemed to run nicer when on the move (a bit more oumph).
Oh well I'll keep looking...[:(]
Mike.
