[Hummer eh!]

current temp -30 celsius. plugged in the H3 (2006) last night (block heater) and it started perfectly this morning. I made it about 5 minutes from my house and engine light came on and Power Failure mode came up on the display. luckily i was by a large parking lot and rolled in and parked. Onstar said the power failure mode came on because of an electronic throttle control problem. i turned the vehicle off for ten minutes, when i restarted it i could get rpm's above 1500 and onstar said the problem was gone, but i still had a traction control problem. drove it home and parked it. can't get tow truck for a cpl days due to the weather, any ideas or input would be greatly appreciated.
