I'm having problems with our LWB Vit. When it is warmed up it's as if the choke is still on.
It idles at around 2000rpm and is 'hunting' slightly. I filled up today and fuel usage is up from around 10L per hundred to 13L.
I spoke on the phone to a mate who is a mechanic he said it could be a coolant temp sensor. Any other ideas?

Have you checked your coolant level in your radiator ?

Coolant level fine... not using any. Temp gauge has always read low.

look for vacuum leaks around the manifold or any lines not connected or broken

This, mine used to do this and I had to tighten up the vacuum hoses with clamps and replace some smaller ones to get it right

Thanks for all the replies will have a good check over of the vacuum hoses this week.
Last Sunday afternoon I drove it to Coffin Bay and it was shocking-as I pulled into the caravan park and the idle speed was quickly changing from 1800 to 2200 rpm. Went for a drive around the NP on Sunday and it ran perfectly?
At the end of the day as the air temperature dropped it started to play up again.
Drove home ok today and was better on fuel again but the idle speed seemed to be speeding up as it got cooler outside.
Thermostat?

Hi,
Im having the same troubles, i have found that its the OAC valve, like your mechanic has described, to do with coolant temps, the valve is in the throttle body and becomes faulty, it senses coolant temp when the car warms up and is supposed to bring the idle back down to around 800 to 1000. I am having one stop suzi shop in the goldcoast trying to source a complete throttlebody to rectify the problem. hope this helps, the gregorys manual explains how this valve works better than i can though.
