Welcome to the board.

I concur on the seafoam, seen good results. I would buy two bottle of it, one full in fuel on fillup, then about 2/3 in the engine crank, then the last 1/3 in the vacuum line connected to the brake booster. There is a write up somewhere which I recommend you reading. Also, you will need to replace your oil and spark plugs. And sparks plug wires would also be good on change.
