I know its attached to the rear of the plenum but has anyone got a pic of it in place? Or will it be obvious when I actually look at my engine?

 

Cheers.

Air regulator - You mean the idle valve, the fast idle valve, or the cold start valve? :D

 

Air Regulator:

The purpose of the air regulator is to raise the idle during engine warm-up by letting additional air to enter the intake.

The symptoms of the air regulator going bad is either low unstable idle during warm up or constantly high idle.

The regulator consists of a bimetal-activated shutter that closes after ~5 min of engine operation and cuts off the airflow.

Note: It's normal that the shutter is only partially open at room temperature.

 

Check the resistance between the pins in the connector. It should be ~75 Ohm. If not good then replace the whole regulator.

Another problem could be that the regulator is clogged, causing the shutter to stick.

The air regulator is located on the rear of the plenum and is attached to it with 2 screws.

There are 4 screws keeping the housing together. Remove them and clean the regulator internals

Ok thats easy :D Follow the hose off the idle valve and it goes straight on to it - kind of cone shaped - you'll see what I mean :)

Nice one Duffster!

 

Give yourself a little pat on the back.

Can he get off now, he's making my legs hurt :(:D

LOL!!! Yeah, send him on his way...... Baggins has asked for him. Think his reasons though are a bit more suspicious.
