Strange

[Cobra]

Turned on the Tahoe today and received a reduced engine power going across the display screen. after a few seconds it went away. I turned it off and checked the codes but it came back with no DTC's. Powered back on and no errors on screen. I wonder if it was just a glitch. Anyone ever see something like this?

Mine has done it before. I believe mine was weather related though....cold weather and a weak battery can cause strange things.
