All of a sudden yesterday I noticed my speedo showing 95mph when my GPS speed was appox 60. Shut engine down when I arrived home and it read 37MPH. This morning still showing appox 34MPH cold with ignition off. Start up and drive speedometer still appox 37MPH high.
Any ideas where to start looking ?
