I have a 2004 C240. Over the summer it would stall when I came to a stop, it would start again after a few tries. Also, everytime I went to go somewhere it would turn over but take a few tries to get it started. I got a new battery which didn't remedy the problem. My husband changed the cam sensor and that fixed it. NOW it's doing it AGAIN!! It's not stalling at stops only doing the not starting on occasion thing. Anyone have any suggestions?
Thanks

 

Does the car go off when in motion?I had a similar problem,I changed the cam shaft sensor,fuel pump and fuel filter and the car now drives well .
