Default AU2 XR8 EFI Problems

The Windsor is chewing the fuel again
Replaced the 02s 2000ks ago when it had the same problem
That seemed to 95% cure it

Now a couple of years later its back to running rich and hunting at idle again
As soon as it switches to closed loop the fuel trim heads skyward, in open on a cold start they start at 18% then fall to 3% till the ecu switches to closed.

The first vid shows how the trims react on a warm start up ,on cold start they drop to 3%

Can someone who knows this system have a look at the two YouTube vids and give me an opinion, Thanks Bret.

Also disregard the Forscan vids on YouTube, that was from last time (4yrs ago)
