2017 Silverado ltz zl1

Yesterday I had engine power reduced alarm come on the dash with the check engine light and traction control light on as well. Pulled over and shut the truck off for a couple minutes and when I turned it on had the same thing and could barely get the truck up the road. Had the throttle half pressed and she barely rev’d up. Shut it off again at my parents for 10 minutes and when I turned it back in had no alarm anymore but check engine light was still on and the truck had her power back.

Asking here because it’s the weekend and nothing open and hoping it’s safe to use for the time being until I can get it in the the garage or if anyone’s see this before and could know what the cause it

 

problems with the throttle body, throttle position sensor or accelerator position sensor can trigger or related wiring can trigger this concern. you need to get the codes read to confirm this and as a diagnostic starting point
