What engine does this truck have in it.....Nissan K21/25?
Hope if you changed plugs you used OEM original NGK plugs,aftermarket,parts store plugs dont work well in these nissan engines...
Guess without knowing what engine is going to be a guessing game......still might be a guessing game after that
