not sure off hand. but incase you didn't know. When that happens just pull over, key off for a minute and then start it back up. Should reset so you can drive normal again

 

yeah turned if off' . . back on . and normal. .. any ideas .. what could of caused this '

 

Reduced engine power is usually caused by an accelerator pedal position sensor fault or throttle position sensor fault.

 

X2 on the TPS in cold weather. When we had a cold snap here in FL (20s from our normal 60s or 70s) a lot of LSx trucks had that same problem and it was traced back to the TPS.
