Thread: Fast Idle problem-94 Disco V8

Thx Phil

Will do. And will take the IACV off and give the shaft and chamber a good squirt of carb cleaner.

She's still revs high, but will clean it and check/replace the sensor and let you know how I go.

Just curious. Is the injection temp sensor the same as the fuel temperature sensor..I'm assuming it is..
Checking the US/UK websites, this part is $90 US. How come so cheap here in AU?

The values are the same but they are different sensors.
The fuel temp sensor is attached to the fuel rail on a Disco I think half way along the LH side of the rail. It's a short button like thing.
The injection water temp sensor sits upright on the RH front of the manifold behind and to the right of the thermostat housing. it has an injection plug on it.
I think that the sensors are not OE but they work OK. Graeme Cooper does not tell where he gets them. Who knows why some parts are priced differently. maybe in UK they can only get genuine or they just are getting ripped off. For example teh IACV is the same as a Chev one.

Phil,
Checked the sensors with my ohm meter. The fuel inject temp sensor is 120 ohms and the coolant sensor is 80 ohms.

Do I have faulty sensors?

No that is OK.
You worry if they are higher. They go up to 4000 Ohms or something when cold. Anything under 400 registers as hot and turns the choke off.
Probably if you turned the motor off you had heat soak which made the temp higher at the sensor
Regards Philip A

I read that these vehicles have no requirement for adjustment of the base idle, but I just followed advice from tech section on atlantic british website and adjusted the base idle/hot idle.

have got it down to around 700-750 rpm and seems to idle better after running in traffic.
thanks for your help anyhow.

Do you know where i can get my hand on a workshop manual reasonably cheap?

The CD doesn't seem to cover the 93/94 model. Or is it a mis print. I'd assume my 94 would be covered. Do I need to know anything before getting the RAVE cd?
