Guys,

Just wondering if anyone knows about the cold start valve on the EFI engines, I am well aware of the 'hot start kit' which are common place on the RV8's on TVR's though never have heard of this before, would this be the valve in question? http://www.landroverspares.co.uk/product.html?cpdI...

Thanks,

Justin

Very strange that.
The part you linked to is claimed to be a cold start injector for a 3.9 but I thought CS injectors were only used on 3.5.

Anyway, I think the bit you are looking for is the IAC (Idle Air Controller) which is a stepper motor which lives on the back of the air plenum. These become gummed up and need to be removed and cleaned fairly often. A simple job as it is just a connector, air pipe and 2 or 3 bolts.
Clean it in some paraffin, quick dry and pop it back on.

Cheers Steve,

I will give it a clean this weekend, its strange she has some issues starting and only 50% of the time in traffic does the engine hunt then cut out but starting again isnt a problem at all. Hopefully this will rectify the situation.
