Idle on Digi

[Godzilla]

I replaced the gromet the other day, no joy    Just been looking through a folder of reciepts that came with my car. It looks like this problem has been going on since Nov 05 with a few invoices saying 'look into rough idle' and a few parts being replaced over the years but with no joy. I felt the ICV whilst ignition on and its buzzing so dont think its that, maybe air flow meter?

My idle stays at around 900rpm all the time even when its started cold and my rev range is full of flat spots. Im guessing i need a new Blue temp sender?

Might aswell put a blue sensor on as part of maintainance mate, costs £14 from dealer. When you have installed the sensor unplug the blue connector and rev 3 times letting it rev to 3k then back to normal before next rev. Re-connect blue plug. Another thing with it sitting at 900 when cold, is your warm air feed from manifold to airbox plugged in or could be perished?

Sorry to be a royal PITA but where is the blue temp sender looking at this pic?



And paul there's a warm air feed from the manifold to airbox? 

This is the most complicated engine ive ever owned, so many sensors and stuff 
I should buy a haynes manual really

Where your dipstick is, to the right of that (as in a couple of inches) is a large hose. On that hose you will find 2 plugs, one black and one blue. These plugs are beside each other. Take the blue plug off and there is the blue sensor

does it have any problem pulling or accelerating? that is quite a good sign of airflow meter malfunctioning. see if you can plug it into a emissions tester an see what it comes up with.

Not any real troubles pulling away. She is a bit flat until 4000rpm, been told this is fairly common and known as 'Digi-lag' to which a good tune up should solve.
