No one responded to my previous post, so i figured i'd try again since this problem is driving me insane and i have yet to figure it out.

Here it is:
My car will shift normally and run fine at 1/4 throttle but any more throttle and it sputters like it's not switching fuel mapping or something.

Also, if i put it in gear and hold down the brake and press the throttle it'll do fine up till 1,400rpm, as soon as i hit 1,500rpm it sputters and makes a rev-limmiter sort of sound.

I have new plugs, wires, and my coil packs are fairly new. Also, i've made sure all my wiring connections in that area are sound while at an idle, and under a load. I have yet to find any problems there.

If anyone has had this problem or can give me any info i'd greatly appreciate it. I'm short on cash so i'm trying to figure out what's going on before i waste my money.

Thanks!
