a major nissan problem is chocking have you cat replaced and put a free flowing muffler like magniflow or flow master if you can find muffler shop that carys them Fullbores they are the same as magniflow and flowmaster but at half the cost and if you have the pipe end right after the muffler you'll have a killer sound to the truck even little street racers will wonder trust me also ad cold air induction to the motor mor power and after thats done go find a mustang gt blow his doors off and and you 'l gain speed up hill and try down shifting to forth untill thats all done but your problem will be solved
