Auxiliary Air Device - 2.8i

Can anyone recommend a scource for these at all?
My one is refusing to close off. Tried cleaning it but no change.
Thanks in advance.

Thanks, had spotted that one.
Thinking there’s a bit more to the problem now, so need to investigate a bit further. Still getting high tickover when warmed up and with blue connector to startup injector disconnected and aux air blanked off. Maybe another air leak that’s opening up with heat? Some quality time out in the garage required I think.

The idle will naturally go up as the engine temperature rises, so you aren't necessarily looking for a temperature related leak.

That’s true but was worth bearing in mind as rpm was very high.
Fingers crossed it seems ok now after doing lots of cleaning of contacts and general checking over, even got aux air device working now.
Thanks chaps for your input. Another satisfied customer

Check the vacuum pipe which goes from the plenum to the Warm Up Regulator. On my 2.8i powered Tasmin the pipe was connected to the wrong tube on the WRU.



Pipe 'A' goes to tube 'B' and not as shown below.

Thanks, all hoses seem in correct place.
All now seems fine since cleaning everything and making sure everything is tightly fitted.
Sun is out, ‘‘tis a beautiful day. Would be rude not to go for a test drive
Again, thanks for the help.
