bunches of little issues

I have an '06 SEL freestyle I purchased about a year ago. It is currently in the shop with 26000 miles on it for several intermittant issues. Has any one else experianced these and or had these repaired:

1. after idling for ~30 minutes, throttle oscillates in reverse from 800 to 1500 RPM. Does not do that in any other gear.

2. After issue #1 yesterday, car would not accelerate past 3000 RPM's in any drive gear, service light was on, and took about 1 1/2 miles to accelerate to 60. Whenever I let off the gas, it felt like the engine would cut out for half a second. Issue was gone the next day.

3. Intermittant airbag light

4. Driver window will auto-rollup occasionally when auto-rolldown was activated

5. I already know this one, but thought I'd include it for someone else's reference-- rear brakes are run out (Ford will replace up to 3 years 36K miles under warranty)

Thanks!

OK. For everybody's reference, Here's what the dealership fixed (they were unable to duplicate any of the 1st three issues)

1 & 2 -- replaced throttle body per service bulletin, inspect and reroute wire harness, re-flash ECU.

3. nothing. there were no codes.

4. replaced driver window switch per service bulletin.

5. replace rotors and pads per service bulletin.

Hope this helps someone else.
