[StickMon]

Any update?
I've been fighting a similar problem for the last few weeks.
Replaced both TPSs and MAF. Still no joy.
Runs fine under throttle. 20% of the time at idle or small throttle it runs rough, spits and pops.
Similar collection of codes. I'm wondering if my throttle actuator is miffin a toof, but I'm reluctant to spend $500+ to find out that wasn't the problem.

Went into limp on me this morning at 80 mph when I had to lift when somebody cut me off.
Forced to do a dead stick landing across about 5 lanes while rapidly losing momentum.
No fun. Did ctrl-alt-delete while coasting in the right lane.

Edit: While I'm on about it, here's some more info for the knowledge base:
Here's my code collection for the day, and this is just going to work and back. Codes were cleared before I set off.

2D07 Throttle flap 1 (is there a throttle flap 2-n?)
2CF6 Throttle valve potentiometer 1, plausibility with regard to air mass
2D09 Throttle valve
2CEE Throttle positioner, sluggish
2CEC Throttle positioner, stuck for an intermediate time

And I discovered a new mode in addition to limp mode. I'll call it "Granny mode", unless it already has a name.
Same yellow BRAKE, EML, and DSC lights as limp mode, but you still have full throttle available.
It just takes a long time to get there. Response on acceleration and deceleration is very slow and deliberate, but the zaniness of the original issue goes almost entirely away, and it gets me where I'm going.
