To the subject...............just ran the car 1300kms this weekend with warmer ambient temps and the intial start up idle is better...........less stumbling.

Concluding that ambient temp has effect........... question is do all temp II, water temp and air temp sensors affect cold (overnight) idle inputs?

Car is smooth after ~3mins of running and remains so.

Air temp sensor has no effect on fuel mixture or ignition timing, just fan operation. Temp II could cause cold start/idle issues if it were reading incorrectly low resistance, but that is usually not the direction of failure. Temp II is the water temp sensor for the LH and EZK.

thx Bill...........to be clear the 3rd sensor mentioned is DS of the water bridge when viewed from the front.

3rd sensor only has to do with temp reading on the dash.
Temp II and MAF are the only ones that control the fuel and ign.

ok.....interested to see what another rebuilt MAF helps.

I've lost track but did you Malcom take a look at the wiring under the rubber boot of the MAF and Temp2?
