Hi Owen,

You've described the exact behavior of our LH2.4 cars when they lack a signal from the speed sensor which drives the speedometer and ABS (if equipped) electronics. The on board diagnostics verifies this by posting a DTC (diagnostic trouble code) of 311.

This VSS (vehicle speed signal) needs to come from the speedometer to the fuel computer, so if your speedometer is working OK, the problem will be in the circuit wiring, most likely at the back of the instrument cluster.
