Problems with 2008 Chevrolet Silverado 1500 ENGINE AND ENGINE COOLING

I was on the highway going 60 miles/hr and check engine light popped on and my car slowed all the way down to around 30miles/hr almost creating and accident. check engine light reads "engine power reduced". *tr

My 1500 series truck has chirping noise coming from engine. currently has 80k miles and noise is not coming from pulley or belts as our mechanic has replaced them and noise still sounds. noise is coming from engine. taking vehicle to dealer. this noise is annoying! *kb

The catalytic converter had strong sulfur smell after the first year. i complained to chevy dealer and was told there was no problem. by year three i complained for the third time again was told no problem the computer didn't show a code. i asked the mechanic to take it for a drive he returned saying the cat was junk it was replaced and i was told only to run top tier gas i did that but after about 8 months it smelled again my truck is just five years old and i need another converter, my power locks have each been replaced three times in second and third year. now i need new airbag sensor and my truck has never been hit . *tr

Vehicle throws code p0128 (coolant temperature sensor). fans run on high, loses power, check engine light comes on. it happens at random. we replaced sensor with a new gm one...but it did not help. vehicle still having the same problem and is still throwing the same code. *tr
