Anyone seen this before? About a min after startup, idle starts hunting - sounds like it's got a big cam in it. You can see on the wideband the AFR is all over the place. Ignition timing is about -4 degrees

 

After about a minute of that, it settles down to a steady idle and behaves itself, goes back to a more normal +15 ignition timing at idle.

 

Has always done it occasionally but seems much more frequent lately.

 

I should data log the cam angle sensors.

Thanks mate. Has brand new genuine coils and was doing it with the old ones so not that in my case I don't reckon.

However... I've replaced a few things as part of a refresh over the last few weeks and the issue seems to be gone. Cam sensors, crank sensor, O2 sensor and throttle body clean - must have been one of them! Although maybe it was changing the diff oil...
