Are you saying that it won't rev past 1500rpm's? If so, you might have a sensor unplugged that might cause that. Or like Nick M said, an exhaust leak.

21-ox sensor, rich or lean for to long, or open or short. .
42-vehicle speed sensor, no signal from spd for 8 seconds while vehicle rpm is beteen 2000&4000 rpm (4400 ge) and neutral safty switch is off..
43-starter signal.no signal till 800rpm while vehicle is not moving.
52-open or short in knock sensor singal..

i would say fix the knock sensor' first...
