ya, the only other thing I was thinking of doing was to go to a junkyard and try to buy the hole intake and computer out of another car. I talked to an import shop in our town and they said I could get $1000 dollars into parts and still not have it fixxed. I was lost too.
have you tried reseting the computer ????..... it could just do it !!... lot of erratic problem could be fix like that when you changed parts and stuff.... just unplug the batterie for 5 minutes... and plug it back.. start the car again let it warm up on idle then shut it down and after that start it again ... should be a bit better !!

What parts has the dealer tried so far? What was the fuel pressure? It's more than likely either the air mass meter or the throttle sensor, in that order.
dealership did all the standard checks , such as plugs , wires , distributor cap ,etc.. he had a look at all the vacuum lines. ive replaced the tps already and adjusted it. is the air mass meter the same as an air flow meter? if my afm was bad wouldnt the car not rev above about 2700 rpm? only does it when the car is warm and under load, ive heard it could be the ignition coil, is that possible?
and the guy who originally posted this who had same problems i have , replaced his afm and it didnt fix anything.

Yes it could be the ignition coil, or about 20 other things. You won't find it until you eliminate the most common offenders for a problem like this. The ecu does not rely on the signal from the air mass meter during cold starts and through the warm up period. The ecu has fixed injection pulse maps for those operating conditions. It isn't until the car warms up and the ecu goes into "closed loop" that the air mass meter's inputs are important. Hence, the reason it runs good cold. Same goes for the oxygen sensor. One other detail, Nissans 5- mode checker box cannot detect a bad air mass meter. That's another reason the dealer couldn't find anything wrong. I'll bet they got a code 55 out of it, [normal].

I can tell you right now, that I have fixed so many of these cars with this same problem, that I would start with the air mass meter first and work from there. I do things differently than most, because I have every spare part for that car imaginable. I don't decide what part to change first based on how expensive it is, I decide by starting with what is the most commonly failure prone. I do all my basic system checks first [like you did] and when it gets to the point your at, I get out an air mass meter and usually, it's fixed.
i had my air cleaner off the other day with the car running , and when the car warmed up, it was burnning oil through the metal pipe that runs from exhaust to air cleaner and tons of smoke was coming out of the end of the pipe with the air cleaner off.yet i get no sut or anything out the back of the car. what can cause this , and how can i fix it?
