1994 Mitsubishi Montero SR 3.5L Poor Idle Quality
Posted to Asian Driveability on 3/15/1999

The problem with this vehicle is simple. It has a vacuum leak at the intake plenum. The variable length plenum 'throttle plates' leak where the shaft goes through the front of the plenum. Has anyone found a fix for these other than the $600 replacement plenum?...
