The truck runs fine on a flat surface but I can barely get it up to 40mph on a hill. I've done everything I can think of to boost performance including changing the oil, Sea Foam-ing the engine, changing the air filter, trying lots of fuel additives and putting in expensive Bosch spark plugs but nothing seems to work. Please help. It is a V6, 5 speed manual. Thanks.
have the same problem?
