02 WRX

Default WRX choking and bucks like crazy

I have an 02 WRX that started having a problem earlier this week. It would run fine one minute, then as I'm driving it would suddenly feel very weird and sluggish. When I go up to stoplights and push in the clutch, the idle would drop really low and almost die. One time it did choke itself out and die, and didn't start back up til about 5 cranks later.

I was throwing the code P1086 for the TGV sensor circuit low. Thinking this might be the issue, I replaced the sensor. Last night I took it for a short drive, and the idle still dropped low at stoplights. It still felt sluggish, especially when I gave it about 3/4 throttle. Then it would be really jumpy/bucky.

If the TGV motor would be sticking closed, it would be throwing a different code, right? Any other ideas what could be causing this loss in power and hesitation?
