Help truck wont go over 2000rpm

So on thursday I drove my truck 1hr 20min one way drive for a work meeting and back again and truck ran good. So tonight friday night I go to drive to work and my truck (1997 Pathfinder 4X4 MT) wont go over 2000rpms. Has anyone had this issue before? Only thing that has been done to the truck between thursday and friday was I install a fresh new air filter... Iam sure that has nothing to do with it. My brother-inlaw has my scaner so I will check to see if there are any codes. Any ideas to look into would be great.

Could be in "limp mode" due to a problem with the MAF sensor. If it is, you wouldn't necessarily be able to tell just by looking at the sensor. Hopefully the scanner will help you.

Dunno about the R50 but on the WD it's easy (necessary even) to mess with the MAF to get to the air filter. If the plug is corroded or loose, this may have broken connection inside. Def check the codes but I'd start by checking the MAF wiring.

Nope just got home and figured I would take a look under the hood and saw the problem. Well I had one of those moments when you forget to do something as important as plug the sensor back in lmfao. Glad that's all it was. Thanks for the advice.
