My nissan pathfinder 2001 slows down while driving

IT SOUNDS LIKE THE THROTTLE POSITION SENSOR IS NOT FUNCTIONING PROPERLY. OR IT MAY HAVE AN EXCESS OF CARBON ON THE THROTTLE PLATE AND BORE. REMOVE THE AIR INDUCTION HOSE GOING TO THE THROTTLE BODY AND SPRAY IT ON THE INSIDE WITH CARB AND CHOKE CLEANER, WHILE ABSORBING THE FLUID WITH A CLOTH RAG. PAPER RAGS COME APART, AND GET SUCKED INTO THE BODY AND CAUSE DAMAGE. AN OLD TOOTHBRUSH WORKS WELL AT DISLODGING THE CARBON. IF THE CLEANING DOESN'T HELP, THEN REPLACE THE T.P.S.. HOPE THIS HELPS. BEST OF LUCK.THANK YOU FOR AN HONEST RATING AND FOR USING FIX-YA. PLEASE KEEP ME POSTED.
