Truck Loosing Power
I got a 2005 Silverado Crew Cab Z71 w/5.3. I have 295/70r17 Toyo Open Country MT tires on it. I was driving it Saturday on opening day of deer season- which means I had a lot of stop and go driving with a lot of mud, water, and dirt road driving. Truck started acting funny about mid day. I could press the gas pedal and it would not hardly go. When it got to about 2000rpms it seemed to take off. I noticed it did not have any take off power. It would not even spin the wheels over on a dirt road. I had to lock it in 4wd low one time and it still did not want to take off. It had the SES light burning and I checked it when I got home and it was for one of the knock sensors not responding. The SES light had been burning for awhile as I have not had time to fix it. I cleared the DTC's with HP Tuners and the power was back. I drove it Yesterday and it was fine till later on in the afternoon. Then it started doing the same thing. I know I could try taking out the Torque Management. I dont understand why it would be fine one minute and then no power the next. The SES light has not come back on and still the power is gone. What could I try the truck is bone stock down to the paper filter. Only changed the tires.

Got it fixed today.
Intake off
A little dirty
Rear sensor
Front Sensor
Front sensor plug
Rear Sensor Plug Notice the stud is rusted completely into. That's supposed to be in sensor.
Rear sensor out
Took me about 2 hrs to do it. It would not have taken that long if I could have found my fuel line tool. For some reason it has disappeared. I had to make a tool out of some hard round plastic to get the fuel line off. If it hadn't been for that I could have had it done in a little over an hour. No wonder that it was throwing the P0332 code for the rear sensor the stud for the harness was rusted into and not getting a good signal. Now to see if that's the only problem I have. Fingers crossed.

did you put silicon on the rubber part of the harness to keep them from rusting again? also you should remove the foam on the bottom of the intake to help release heat and keep crap from building up in there.
sorry i know this info is alittle late.
