I did a 0-60 run with me truck tonight, got back on the highway and she went into limp mode. ther is no CEL and oil pressure and temperature guages are where they should be. any ideas? could the computer just have sent a bad code? is there a trick to getting it out of limp mode?
 
Does it say "Reduced Power Mode" on the DIC?

When this happened to it turned out to be my HID's... 06 Sierra. Installed a relay harness and it never happened again.

same i had HIDs put it in limp mode, it would mess up the throttle position sensor or some shit, i would shut the truck off for like a min, start it back up and it would be fine. or i would just clear the codes that were in the system and it would be good to go.

I have a feeling thats what it is then because my drivers side light went out before the run. Thanks guys. I unhooked the battery and it seems to have cleared the code, now time to buy new HIds
