Mercedes CLK350 2006 occasionally starts running rough, has burning smell...
I have a 2006 CLK350 2 door convertible and this problem started last summer where I'll
be driving then stop at a red light and start and you can hear the motor revving and the
rpms will go up to like 5 but the car won't get over about 40 mph and it rides really
rough. So I have to pull over, stop the car, turn it off and turn it on again and it's fine. It's
an intermittent problem but the time between when it happens has decreased so I think
maybe a sensor is going bad but I'm trying to figure out what it is so I can tell the
mechanic. Any ideas?
