My 94 +8 is a manual gearbox but I once had an issue with the engine stalling when coming to a stop at junctions or traffic lights. The faulty code shown was 48 the Stepper Motor, tried a few new ones but could not resolve the issue. Finally I got to the Road Speed Sensor, cleaned the screws attaching it to the bodywork making sure the earth was good and the issue was solved. For good measure I also checked and reset the Base Idle along with the timing which made a considerable difference to improved performance.
Thats very odd as theres no connection between the circuitry inside and the body of the speed sensor. The two wires simply connect to a reed switch and resistor in series. The rotating magnetic pickup opens and closes the reed switch. Theres no connection to earth via the casing. Still worth a go as its easy to accomplish. Thanks
