So I recently changed the starter and checked the alternator for problems and changed belt an battery and spark plugs and cleaned maf sensor and knw my car is starting to buck ones in a while when I hit 40-50 mph and when I come to a stop it will sometime turn off. The only code that came on was the maf sensor and there is no check engine light on.

 

Replace the MAF, clear the codes and see if that fixes your issue. It is not very good if your MAF is gone.

 

Did you use MAF cleaner? If not, clean it again with the right stuff. Although the wrong stuff might have screwed it up.

Before you replace the MAF, you might try fixing it. http://forums.maxima.org/4th-generat...lem-fixed.html That worked for me.

An MAF code doesn't trigger a CEL? Are you sure your bulb is good?

 

Yup.OP, Eeectrical parts cleaner from Radio shack is my choice for electrical car components like the MAF.
