Hi,

Boy I am glad I found this forum!!!

Anyway, i'm a newbe, and I have a 2000 Maxima SE with 71,000 miles on it. I love the car, execpt about 2 months ago it started bogging REALLY bad when it hits 3,500 RPM. The best way I can explain it is if it were a 2BBL carb motor, when the secondaries open up the engine would flood out. I can't get it to spin higher than 4,000 RPM now....

Also, if it is in neutral, I can spin the engine upto redline. It is only when it is in gear. It has an AT, if I put it in first, it sitll happens....

It started about the same time that I had the computer reprogrammed by the dealer for a TSB about the O2 sensor, and it was putting on the idiot light.

I hate my local dealers, and can't find a shop that I trust!!!!


HHHHHEEEELLLLLPPPPP

 

Sounds to me like the Mass Air Flow meter. If you manually search this forum you will find out how to replace it and save yourself about $300-$400.

 

I had the same problem that you are experiencing....I cleaned my mass air flow sensor and all was solved! Car running awesome ever since.
Clean it before you replace it.

 

get this at your local dealer, $100 or so. Updated MAF...will eliminate the lag

 

$100 bucks? my dealer wanted $140 for it...those thieves...mine just blew and i just got it replaced yesterday...luckily i had the service + warranty so the ridiculous $400 something total cost was waived.

 

I checked with several local dealers, which ranged from $100 to $125...each dealer makes their own pricing based on stock and demand. This one is actually a "spare" I carry on long road trips, just in case, for peace of mind.

 

Thanks, I will take a look!

I read through the TSB that are listed on this site, and found the one about the tranny slipping. The more I look, this could be the problem. If I am out of gear I don't have any problem red lineing the engine. But when going up a hill, if I punch it, or have the throttle more than 1/2 way open it bogs/hesitates.

I think it is because it should shift into a higher gear but it isn't.

I will take a look at the Air-flow meter.
