-40C under controlled conditions... so try starting a used old engine.. at -20C...

 

Thanks for the info. I'll get on the O2 tonight and have my antifreeze tested.

 

I changed the O2 sensor (B2/S2), few cycles later i got P0152. B2/S1 is now on order. As for starting last night and this morning...it was fine, however its warmed up to -24 or so today.

Hopefully i don't get anymore codes after i change this upstream sensor. Fingers crossed ; )

 

The upstream sensors are more important than the down stream sensors.... that should fix your idle problem for sure.
