I have had absolutley no problems with my 300E for over a year now. yesterday I noticed that at barely costing speeds it would almost "buck" (the RPMs would fluctuate between 5 and 10).

I had just fueld up and thought perhaps there had been water in the gas so I added a bottle of dry gas at the next stop.

The dry gas has not fixed this challenmge and the gas mileage has gone from great to YOU GOT TO BE KIDDING ME!!!

I'm still thinking fuel, perhaps change the fuel filter?

What do you all think?
