An update. changrd coolant sensor today and car runs better and cured idle to 1800 and splutter, but still idles around 1250 hot 1050 cold. have checked for leaks again but nothing,tps spot on 0.4v,unplugged aac valve and no affect. any other suggestions?

A ~1200rpm idle is not out of the ordinary on these cars. Personally, I'd live with it.

after sensor change and reset ecu car settles around 1350 hot but about the same intial startup but then whilst warming up drops to 1050 then eventually back up to 1350? If i unplug air temp sensor on plenum hot / cold makes no difference? If i unplug idle valve when cold idle speed drops but makes no difference when hot? any suggestions cheers
