Hi all,
Newbie here! Just got a 1999 Series 1 Discovery Auto V8 3.9. It' s got an idle problem. 104k km's (c70k miles)
Pulling up in trafiic/lights etc. the revs can drop to the point of stalling and then may recover. Had all sorts of parts replaced: fuel pump, Air Mass Sensor, Temp Sensor, replaced all filters, cleaned throttle body and idle control valve. Problem is better but still there.
Searching the internet, I keep coming back to the Vehicle Speed Sensor (is that the same as the throttle position sensor??). There seems to have been some good write-ups to replace this part, but they don't seem to work any more. Can anyone send me a write-up to replace it or is there a way to test whether this is my problem?
I believe the Throttle position sensor is part of the Exhaust Gas Recirculation System whereas the VSS is part of the Fuel injection System.
Can anyone help? Not even the dealer has been able to diagnose the fault and I'm now getting disheartened.
Thanks
Ben
