I have an 86 300E that acts as if the engine is loading up. I'd say a float were stuck if it had a carb. It runs fine until you start to decel or cruise at a constant speed for any length of time, as long as you are in the throttle it runs good. I have done a complete service and tune up (everything has been changed). Anybody got any help?
