This is a $4000 repair and it will keep doing it at the most precarious times. It won't "go away." Mine started it 2 weeks after I'd bought it. I wonder how he got it to "suppress" while he was closing the sale with me. I forget what the part is; I must have a record of it someplace. If so, I'll get it to you.

Very embarrassing considering you're driving a Mercedes.

it is the sign of a bad air flow sensor change it i was having the similar problem on my 93 sl600 disconecting the passenger side was making just a littel change in rpm but driver side was making the rpm go up and down like a rough idle i changed the driver side it didnt do much then i changed the passenger side then it was working fine so i had to changed both of them
