Sounds like your timing is off.

what maf are you using? I know that happened when my stock sr maf was bad! if so try getting a sohc ka maf with the pig tail and try it, or just spend the money for a z32 maf w/pigtail, you'll need it eventually!

2500 = MAF. unplug your maf while the car is running and if the idle smooths out and sounds different...

when your maf is unplugged or broken you cant rev past 2500rpms.

Make sure you MAF is wired right. If you mixed up the wires it will not idle and will not rev past 2500. The wires are very easy to mix up. Good luck.
