Hi again. My CLK 320 auto 2004 petrol in question here. Started to notice a struggle for it to stay alive when idling in traffic. This morning on the way to work after stopping at a set of lights she refused to rev and I pulled over. Pressed the accelerator very gently and got up to about 2000 but then she went back to a slow idle 600ish and then no pedal at all as if it was broke! Turned off and then restarted and all was fine -ish. There is a definite slight flat spot on pull away, needs a bit more pedal and then pulls away quickly rather than smoothly. Any advice please, thanks.
 
I can't help, best get the codes read using MB STAR diagnostics before throwing money at it.
