Hi,
I wonder if anyone has had this problem.. My Altima V6 hesitate when accelerating above 2500rpm. I have cleaned the throttle body, but have improvement in performance. The car has 65000 miles on it. At 2500 rpm the engine cuts out, then resumes running. Holding down the throttle pedal results in bucking action. Below 2500rpm everything runs good.
Can anyone help me?

Did you ever get this fixed?
This sounds like a MAF problem for sure. Go to Pepboys or call some part stores to see if they have a MAF for your car. The MAF is a lot cheaper at Pepboys vs the dealer, around $200 vs $400 plus at dealer.....and it's very easy to replace.
