Re: 1995 LeSabre engine revving (Accelerating)

I don't know how much the 95 differs from the 2001 but recently fixed a similar problem. It was a bad idle air control valve (IACV) which is on top of throttle body. But it could be other things. With the, car running and park with parking brake on, Check the throttle linkage and springs to ensure no binding and smooth operation. Push on the throttle plate to close it to see if that makes a difference. Search forum for checking and chasing iacv.
