Have you done a boost leak test? Have you replaced the spark plugs and/or wires with the proper NGK plugs and wires?

Check your plugs for starters. I would than check for boost leaks.

By: "falling flat on it's face", you mean that it just doesn't go anywhere? Feels like it hit a brick wall? Engine revs fast and car doesn't move?

it drives but it feels like it hits a brick wall then drives okay right after that.

You're hitting fuel cut. Do a boost leak test ASAP.

 

[rush2252]

do you have the recirculation hose hooked up or are you venting the blow off valve? Usually a backfire is caused when you try to let it vent. It sounds cool but runs like poop shit at higher rpms. The hose im referring to is shaped in an S it runs from the plastic BOV back to the fresh air located after the mass air flow sensor and air box on the passenger side.

Also check your hose clamps on all air intake hoses. The one on my main hose going into the TB was loose (air leak) and it felt like hitting a brick wall only under heavy load (idled and cruised ok).

i figured it out! the boost leak was the intercooler piping it wasn't hooked up right
