without taking it out or replacing it? Cant be fuel pump as it would be good or bad.Fuel injectors and sensors cleaned.Hesitates and bucks going up hills.Fine driving on flat --no problems then
nope if convertor plugged its plugged but id guess and say your car just needs a tune up going up hill puts a strain on motor and if one plug is bad wil do that also coul dbe dirty fuel system so id replace spark plugs and try a bottle of fuel treatment before replacing convertor when convertor bad car might only run 45 wide open
