Upon acceleration sometimes light other like going up hill my engine sounds like it rattles or spark knocks. Just idling its fine. I've tried several things, I used a can of seafoam, then Star Tron fuel treatment, then lucas fuel treatment, ( different times ) changed to non- ethanol gas, funny thing is sometimes it runs great.
have the same problem?
