I don't know if it
2005 Chevy Avalanche.And you did the Throttle body sensor. Reduce power light coming on, APP and TPS that a shot in the dark, As for the EGR if that is a problem The vehicle is a speed density it also uses a MAF (mass air flow) . Whenever that light comes on I'm finding it in the transmission parameter not the TPS or APP (accelerator pedal position) first the 2005 Transmission has a high failure record, There is a transmission pressure control solenoid that is given wrong input data and send the transmission to self destruct. If this is your second problem similar to last year go ahead put a throttle body sensor, but the APP need to be in sequence with it. As for the EGR no it wont cause sluggish failure it is monitored by the MAF if the MAF fails then its back up by the MAP. For the reduced power light get the ECM reflashed

2004 Chevy Avalance CHECK 4WD light
I had that problem to last winter too. i took it to a shop and they told me it was the 4x4 switch. it is a common problem. I changed it and so far so good. It was an very easy fix. you just pop off the dash all the way around then you can take the switch out. there are two clips one on the top and one on the bottom. then all you half to do is un plug the wires and you are ready to put in the new one. it only cost me around $130.00 canadian.
