161,xxx miles. Fuel pump/filter could be the issue. Where is the filter on these?
If it was the pump wouldn't it just not work? Do they slowly go bad?

Thanks for the replies
Sounds like my exact thought progress (and my tuner's) when resolving my issue. My fuel pump went bad over the course of about a thousand miles. First, it began sputtering and hesitating only at WOT every once in a while. A hundred miles later, sputtered every time at WOT. stayed like that for 500 miles, then one day it was horrible. If I was in boost AT ALL, it would sputter. The last hundred miles before I changed the pump, the car was not driveable. It could barely get to 3k rpms, had like a 20 second 0-60, and felt like I was constantly engine braking. This had occurred after replacing the spark plugs, compression test, coil pack testing, and smoke testing (and fixing small Vac leak). The car wouldn't even start the day I was replacing the fuel pump. After the install, she ran beautifully again (after I replaced my front O2 sensor because of a poor idle and constant stalling)
