My GST Shutters when I accelerate.

[chr0n03939]

Hi, First off i'm new to these boards, i did search for my problem but i couldn't find any helpful info. Bascially what happens is when i press hard on the gas pedal, my car shutters and it doesn't seem like i am getting any more power. I don't know what is happening. Any help would be greatly appreciated, and i'll give more info if needed.

Also check your fuel regulator....and filter...I replaced fuel reg. and she accelerates fine till 4k becuse of leaking/or bad turbo....I have no leaks...

My guess would be either a boost leak or your spark plugs/wires. First I would check the spark plugs and wires. If the plugs are clean, don't worry about them. If the wires are at all cracked or bare, they could be grounding out on the valve cover under a heavy load, and starving your engine of spark. This happened to me on my car (especially if the insulation gets melted by your valve cover).
