Why does my car seem to rev while in park?

What is your question?

While my 2001 Chevy Malibu with 192XXX miles on it is in park it will occasionally begin to rev on its own. In addition when it does this while it’s not in park as soon as i let off the brake it will lurch forward and accelerate itself. I know it’s an old car but is this repair feasible?

How long has your 2001 Chevrolet Malibu had this problem?

A week or so
