Ok,,,this Thing Idles Great,,,,takes Throttle If You Push It Real Slow To About 20% ,,,and Will Rev To 3800 Rpm ,,,when You Try To Give It Any More Throttle It Falls On Its Face And Pops And Sputters,,,wont Stall Even If I Push It Wide Open,,,turbos Are Spooling,,,getting 4-5 Psi On The Gauge,,,seems To Be Way Too Fat At Idle And The Pre-cat Is Heating Up When I Try To Get It To Rev Up,,,it Acts Like Its Leaning Out When I Try To Give It Throttle,,,all My Sensors "seem" To Be Working Fine,,,i Havent Been Able To Hook A Scanner To It Yet,,,tomorrow Is A New Day Though!!

 

Precat is clugged

 

Is It Possible That Its Really That Simple?? I Figured I Had A Gremlin In The Fuel System Somewhere,,,just Couldnt Find It!!

 

I THOUGHT OF THAT ,ANY ONE HAD ANY SUCCESS CHECKING OR GUTTING ONE OF THOSE???

 

I find it easier to read if you just use lower case letters, rather than alternating between all caps and caps on every word...

Plenty of people have gutted the pre-cats, but it's a lot easier just to buy a downpipe from one of the myriad number of aftermarket places that offer them for the FD.

 

Precat + fiber wrap = sexy

 

I certainly am after reading this thread!

 

I had that same problem. Turns out it was my ecu going into a fail safe mode beacuse my car had over boosted. My advice would be to check and clear any engine codes.

 

If it is the no matter what you should replace the precat. It will fail eventually if it hasnt already. Downpipes are cheap as hell on the for sale section of the forum. I got my HKS ss downpipe for 110 shipped.

Also, I would check your plugs. I had some stuttering and ignition break-up when on boost, then i cleaned my plugs and it fixed my problem.

Pulling the codes off the ecu doesnt hurt anything either. It only takes a few seconds to do.
