My 1994 Chevy Suburban has a knock in the engine......?

[burnsboy1]

My 1994 Chevy Suburban has a knock in the engine after it gets warm. It gets louder when I turn on the AC during the summer and it is throwing off my Knock sensor and TPS sensor giving me less power when I press the gas pedal. What could this knock be? I was told it could be my flywheel or my crankshaft???????

I thinks it may be a Rod and spring.......IDK

check the timing chain and gears in it when they get worn down they will cause a knocking noise and will also throw the timing off as well as other things and make it run bad,that would be the first thing i would check Chevy,s are notorious for wearing out timing chains and gears in them once they get past 125 thousand miles,good luck.
