whing noise from throttle body during heavy accleration

I have a whining whistling noise coming from the throttle body of my 1990 ford f150 under heavy accleration. Any suggestions on what this could be.

What engine are you running?? Have you visually inspected the throttle body? Removed air inlet hoses,etc. You can take some throttle body cleaner and give her a good cleaning and see if that helps.

The trottle body gaskets on these trucks had problems with sucking the tb gasket in creating a vacuum leak. Could be that.
