AU falcon issues (speedo and off idle performance)
in the last couple of days some oddness has crept in to my AU (Nov 99 build, Auto,I6) XLS ute, its done 3000km since its last service and has been faultless until now.
2 things have started, the car can be idling in park or neutral and (especially when its cold and idling higher) the speedo starts to register anything up to 20km/h (which makes the park brake warning start)
the other is that the off idle performance has developed a stutter for 1 or 2 seconds before smoothing out and accellerating.
anyone know what might be causing this?
