    Engine help!

    My engine has like a high pitched screech. When idleing it comes in and out randomly. When I'm cruising without giving any throttle it will come up and I give it throttle it will go away. Does anyone have a clue what it is ?

    One of your belts need replacing, Or one of your idler pulley's are about to take a poo on ya.
    Start the car, pop the hood and try to pinpoint which belt it is, either A/C belt or Main Serp belt.
