Default HELP! Throttle doesn't work!

I unplugged my rear O2 sensor for maintenance and the car revved up to 5000rpm by itself then back down to 1200rpm and stayed there! Now the throttle doesn't work, it just idles and I get the following codes, they won't clear:

2 Faults Found:
18039 - Accelerator Position Sensor (G79): Signal too High
P1631 - 35-00 - -
18042 - Accelerator Position Sensor 2 (G185): Signal too High
P1634 - 35-

Default Reset your ECU...>>

You unplugged it while it was running? Probably not a good plan.
