This is my 2008 C 350. It has 80, 000 miles on it .


Have a problem that I cannot figure out. When I start it the rpms go way up to 6 then down and up again. The car wont accelerate past 15 mph and jumps up and down. Car is having breathing problems. I took it to Firestone because I was on the road when the issue happened. They stated their computers system cant pick up what the problem is. The manager said it has to do with a sensor or an electrical problem and to take it to the dealer. Anybody experience anything like this before?

Firestone was able to reset the codes and the car drove perfect and got me home. However, they stated the problem would happen again.
