Thanks guys,

So I got one from A Parts in Malaga and it was second hand of course and everything seems to be fine and stops the problem of clicking on and off like the old one did but when I switch off my car the check engine light stays on for about 10-15 second and then went off... is this normal?

The check engine light is very faint too so it's weird...

All this started on Friday when I swapped my std wrx cluster to the same year sti cluster I got from eBay.. all the plugs are the same and it was a plug n play with all the speedo, tacho, Fuel, temp all functioning normal inc the ABS And Airbag Light On and Off.

The cluster wouldn't have caused this would it? Because this stepper motor problem started last year where it was idling very strangely and Subaru cleaned them up saying sometimes it will be okay but if it comes back the. Needs to be replaced.

Help please guys, it's doing my head in.

Subaru said if after replacing the IACV and it's still doing that would need to be plugged into computer to run diagnostic but because I've got an aftermarket Link ECU, Subaru won't be able to diagnose it
