Upon leaving a store parking lot codes P0220 & P2135 were set. The digital readout in the driver info center spelled 'REDUCED ENGINE POWER". The engine would not rev past 2000 rpm (6.0 ltr gas in a 2005 HD2500 Silverado). Once home my ACTRON scanner ID'd these codes. Codes were cleared and all is now OK.

I had the same problem with my 2011 impala. Lost engine power and my brakes gave out. I parked it and turned it over a couple times. It's working fine now but it was a little sketchy. I'm going to drive it back to work which is about 15 km away from where I live to assess it. I made the mistake of not warming the car up with it being -15 degrees out in conjunction with a heavy hoar frost that's set in. I'll follow up tomorrow.
