Evening all after much battling and removing of Turbo plumbing I managed to change the DME coolant sensor today. It did not however cure my problem of rich idling. I am not disappointed that I did change it though. So I have checked the throttle position switch and that is working fine and the resistance readings of the new coolant sensor check out just fine. So what else could be causing it? There is no mixture adjustment so what's left? I can only think of the AFM but that was changed just last year. Answers on a postcard if anyone has any ideas.
