Reduced power mode code p1516 Okay guys I have an 04 Silverado with a 416 turbocharged engine and I have the NW 102 throttle body with the x link adapter.(I'm using the original trucks engine harness) Just yesterday it started going into limp mode. It seems to only do it when I'm decelerating or when it's idling. Have ran it for a few weeks with no problems and this just started so if anyone has any ideas that would be great thank you!

Could be the adapter or the pigtail to the tb.. try checkin the wires on the pigtails.. i believe it could be the famous brownish wire that usually is the one that breaks.. ur last resort could be that ur pedal is messed up..
