i have the same truck. i took it for a tune up, after that the trucks rpm's ran up and down. shops wanted $125.00 to tell me what was wrong, u know what told them.......! I didn't fix it for years. then i took an auto electronics class just to see what i could find out. i looked at another nissan in class and discovered two small hoses from the air cleaner in the front to that branch of tubes, in the front, had been swiched around. question remains, did the tune-pu guy do this intensionally? the hoses do not cross, they drop down into positon, hmmm.

hope this helps.
