problems with my car!!!!

[talontsi9095]

Ok let me start out by telling you i havent done anything to the car besides getting tre to build my tranny and reinstaling it and a new clutch the previous owner did all the mods. Well the problems didnt start till after i got it built and and put it back in well my car is a 95 talon tsi awd with a 6 bolt with the following mods RC 550 Fuel Pump Hawn upper intercooler pipe Griffin front mount intercooler Custom forcedperformance lower pipes Poly motor mounts Greddy Type S BOV Ingen intake 16G Turbo RRE down pipe RRE test pipe Thermal 3 Inch cat back Apex AFC Greddy Turbo Timer Greddy Boost/EGT gauges Ported 2G exhaust manifold B&M Short throw shifter Welded center diff ACT 2600 ACT Street light flywheel 6 Bolt Swap Weisco 9:1 pistons Egale rods Balance shaft delet Balanced internals ARP head/main studs New front cover and oil pump i copied and paste cause im lazy but anyways the problems are that it will not idle at a cold start it dies everytime unless i hold down the gas. When it warms up it doesnt idle well and when im driving it it will sputter at a constant throttle and just lately when i give it full throttle it will sputter very bad its progressively getting worse! ive already replaced my plugs and plug wires and im thinkin its a leak or somthing of that sort in my intake! so if anyone can help i would really appreciate it! thanx oh if you need to know more just ask!

First thing you need to do is run a Boost Leak Test. Secondly, I would Test the ISC.
If all of this checks out okay, then I would try replacing the FIAV (Fast Idle Air Valve). However, your problem more than likely lies in the Boost Leaks, or the ISC.
