1995 C280 Engine Problem?
Purchased a 1995 C280 earlier this week. Car ran extremely well until last night. After exiting the Interstate on a brief 12 mile stretch, the car was idling very rough. At first I thought an engine mount had broken. Turned off car and went shopping for a 1/2 hour. Started car and it ran fine with this symptom eliminated. Once again, took that same short trip on the Interstate, only to have the rough idle start again once I returned to surface roads. The only thing I've done to the car is to fill up the gas tank with Premium blend. The tank still had about 1/4 left of what the previous owner had in it. Any suggestions as to what this problem could be? The speedometer gauge also stuck at zero on the 2nd occurrence. Thanks for your help.
And yes, I used it for Interstate travel prior to filling up the tank with the new Premium and did not have this problem.
