I have a 2004 1.6L petrol focus and have the following issues:
- Revs hunt at 2200rpm
- Speedometer reads 0 but fluctuates with revs
- Speedometer intermittently fluctuates whilst driving
- RPM's drop to below 700 when clutch is dipped i.e. approaching a roundabout, but then rise again
I suspected the VSS so replaced with a brand new one from ford with no success. Also I have removed the dial cluster and cleaned with electrical contact cleaner and moved sensor wiring loom away from HT leads and coil pack to eliminate cross talk.
With the VSS disconnected the issues are still present.
Any ideas ??
