Hi everyone, as mentioned, car is warm and running, ect at about 85 degrees C and after wondering why the idling has been surging about I've noticed its going into Open-cold fuel status when in fact it should be in closed loop which is really messing about with my idling.

The idling then fluctuates between open-driving and open-cold between 1250rpm and 2100rpm.

After a couple of seconds it'll switch into closed loop and then idle at the set 1000rpm and hit target a/f.

Any ideas why its doing this?
