Hesitation at high RPM's

[tommy583]

I also forgot to mention that I have a chirping sound upon hitting the gas. It happens more when i let out the clutch ( under load ). If i just hit the gas in neutral ( wife helping ) then it's just a quick chirp, instead of a few chirps. I'm thinking after replacing the belt, I'm putting more stress on a pulley or the water pump. Or after searching the threads maybe the tech didn't snug down one of the spark plugs when he replaced them. Could any of this ( Original Post ) loss of power at higher RPM's and Chirping be related?
