my car hesitates when i hit the throttle. im about to do an Al-Quaeda bombing on my car. please see sig for full details on my car.

things i have done/checked:

-valve adjustments
-fuel pump primes
-fuel reaches rail
-got good working injectors
-compression 160's
-plenty air (boosted)
-timing i checked about 200 times
-new distributor
-new spark plugs
-clean gas
-checked all grounds
-checked all fuses

things i havent done/or might be faulty:

-changed fuel filter
-i suspect my map sensor or TPS sensor or crank fluctuation sensor (by crank pulley) might be faulty
-its got open pipe now since i got my turbo manifold and didnt match up with my exhaust system
-put the timing light on...even though im 100% sure timing is right
-got crv timing belt instead of ls (but its got same part number)
-got check engine light but dont know what is causing it

so with those in mind. when i hit throttle my car goes for a second and then acts like its either not getting any fuel or air and my rpm drops and car almost dies. im about to give up because this project has taken me about a year to complete and im tired of it.
