Sorry I have not replied sooner I never knew you had messaged as I didn't get an email lol
My ECU is a 3H 22611 AF633
I have not tested or replaced the coolant temp sensor, how would you recommend I do this by checking the resistance in some warm water obviously disconnected from ecm and what pins would you use ?? Also the ECU is reading like 20 degrees which I would suspect it to be ok.
It is out of an Impreza and is SOHC
I have ordered a new IACV but is a cheap one and most likely be the correct one as the seems to be so many different tyres Nd import car part don't do
