throttle position sensor .. this lets the computer know just where your foot is on the gas .. It gets worn out in that position because that is where it is used the most. I would check it first then go from there... they are priced reasonable .. always start with the least expensive first then go from there. thanks Jerry holler if you need more

I dont use this word much but im Assumeing that YOUR mechanic scanned the computer and checked the coolant sensor or other possible causes,Ive ran across this many times before so bare with me,Have your mechanic try a known good Airflow meter and dont forget to check the main airboot for rips,cracks or tears in the seams,gotta inspect all the areas where it is accordianed for flexibility,another one is moisture penetrating into the distributor cap,got more if ya need them hope this helped let me know have a good day Darrell

disconnect cable connection at throttle body by loosening retaining nut and removing cable from attachment. follow cable to firewall and disconnect cable from fire wall a rubber grommet may need to be removed with a flat blade screwdriver and gentle pressure. under dashboard, at top of gas pedal,cable is attached by clip,disconnect. and pull cable through and into vehicle. reasembly is reverse. when connecting to throttle assembly make sure there is about one quarter inch slack in cable.

Most likely need to replace you accessory drive belt. However, before you do that make sure the tensioner is bringing adequate pressure to bear on the belt. The squealing is probably the side of the belt slipping in the metal drive pulleys.
