01 pathfinder loss of power and hesitation - help

[backer01]

01 pathfinder - when driving I can hold the pedal to the floor and only get to 30 mph. When power returns, I only get about half power back. I've checked the air filter, replaced the fuel filter, cleaned the mass air flow censor. If you have any ideas please help. -Ignition coils?-Bad plugs?Seems like the car isn't getting any fuel and/or air. It's driving like it has a really bad hesitation.

Bet it's the knock sensor and put your truck into safe mode. Won't kick the SES light either.

check your transmission. have you ever changed your a/t fluid? if not then get it done sometimes soon.
