insufficient coolant temperature for closed loop fuel control

does anyone know what that means?

 

are you running a 160 deg thermostat on an '03 or newer? The newer ones don't seem to like them....

 

just put it in 3 days ago

 

others have had the same problem, I think you'll need a 170 deg to fix that............not sure though...

 

makes sense to me thanks

 

happens when your engine can't heat up enough to do their emissions thing. Happens if your engine doesnt heat up to temp after a period of time, like 20 mins or so. If it's still cold where you are you should probably try the 170 stat and then you can try out the 160 again in the summer.

 

temps here droped the same day light went on

oly chit that was pretty good guys thanks
