WARNING: This page is about a different car, the 1997 Volvo 960. However, it is still accessible from the selected car via links, so may be relevant.
Throttle pulley should move freely without sticking. Cable should be taut in idling position, without altering pulley position. Pulley should rest against idle stop. See Fig 1 . Adjust cable as necessary. Press accelerator pedal to floor and ensure pulley reaches full-load stop.
