sounds like a flat lobe on the cam or a rocker has come apart... pull the valve covers and make sure all the rockers move close to the same.. I never did like using those engine cleaners on high mileage engines... you just loosen up small chit and it gets stuck in stuff... leave in stuck to the oil pan where it wont hurt a thing..
