need help fast!!!!!!!time sensative

this has been goin on for like a couple of weeks but not all the time ...i stoped doin it because of this.....every time my car hits high boost and i push it to maybe 6000rpms or a lil less..starting from first gear and on my car will make a loud pop and the whole car feels like it made a complete stop...or it tryed to stop while it popped...any info to what this could be please please right back

its called fuel cut. where your car is either running too high of boost or not getting enough fuel the car will cut out for a second. Its normal for turbo cars to do it, but not all the time. What boost are you running? what mods? It may only be something small like a fuel filter or something but more info is needed

everything is stock except the mods that are listed in my signature...um more info....let me see...first off it scared the **** out of me...because i was tryin to see what i did in 0-60 but then i hit like 6000rpms in 2nd and then bam a loud ass pop and the whole car like shook hard my boost is stock so is my fuel...how do i check for fuel cut....could this be my tranny...(hope not) well thanks for ypur reply...

I would check all the connections in the turbo system. Sounds like you are blowing off your psi at some point. Check the intake at the throddle body.

no fuel cut has nothing to do with your tranny. And it is exactly what your car is doing is fuel cutting. Do a search. Ill try and find a good thread to read on it for you. Most likely you dont have anything major wrong. All it is, is the computer cutting off your engine basically

i guess this will help a little. http://www.tmo.com/faq/diagport/970929.htm

damn i think that was right on point...thanks alot man appreciate it..thats helps a hel of alot ...so i guess i would just buy Stage II ECU modification, what exactly is that and do they sell this kind of mod...or is it pure custom...and another off subject thing i was wonderin ...i own a 97 gst spyder and i was wonderin where could i go to get a custom top like a lid...like the s2000's have hard top maybe fiberglass

i dont think they make hard tops for the spyder. And as far as fixing the problem, i dont think you need an upgraded ECU. I think its something else that is causing. But anyways, usually people willl have to modify the ECU only when they want to upgrade fuel systems, increase to high boost, ect. you arnt doing any of that right now so its not the ECU. I would try and replace the fuel filter since its an easy fix. Or maybe air filter. Just do some general maintenance. Remember fuel cut is normal for a 2g car to get from time to time. So dont worry too much about it. Its not hurting your car even though it feels like its really bad. Its actually preventing bad stuff from happining

still hitting i need a cure.i cant hit the gas ohit 6000rpm without this happn...fuel filter is ok stock boost.. leaks...what can i do

Fix your boost leak(s), upgrade your fuel system or turn the boost back down.
Find and fix your boost leaks first though.

Your injectors may be bad...  Maybe even taking them out and cleaning them might help.

where can most leaks be found..piping?....intake?

You'll have to do a boost leak check to find them bud.  Yes, the intercooler piping are where they are usually found but there not commonly found on any particular bend.  The throttle body, intake manifold, fuel injectors, and even the PCV can be leaking too.

thanks
