Hi there from freezing cold Fredericton New Brunswick Canada.
My wife has a 1999 c280 sport w 107.000 kms that has started to give her some trouble.
We have owned the car for 3 years and have had an extended warranty for that time.
We have done the crankshaft balancer, mass air flow, electronic climate control under Warranty.
The problem now is that upon starting the car it will start and then the R.P.M.s will fall and almost stall or stall the car at start-up, it will recover and idle fine.???
We have not changed the plugs, wires or battery
Any thoughts why this might be occuring.

Thanks
Lance.
