what are the most likely things to cause this? timing is ok. what are the common things that go on XEs that would relate to this?

oh and faulty CTS can cause over fueling aswell
If you look on mig you should be able to dig up all the voltage / resistance figures to test the AFM co adjustment and prob CTS aswell

When you adjusted the screw to an extreme amount ie. fully in or fully out did you get an ecu light?

Thats a bodge as you are compensating for other problems.

NO
On the early xe the CO adjustment screw is used to set the mixture across the rev range as there is no lambda. As i said it has to be set to specific values which can be done either using a millimetre of a CO tester.
if winding the screw right in / out has no affect on idle and doesn’t give EML I would try a different AFM
I would also look into CTS as well though, but usually if the CTS is to blame it will be over fuelling terribly and run very poorly

AFM was brand new bosch one 6 months ago, will try cts at work tomorrow, see if it makes any difference.

you should get code 65/66 If you run to rich or to lean on the AFM, but the fact that idle changed would suggest that it is working to some extent.

it could be the delco ecu have that checked when you have exhausted all other routes if you need the ecu tested send me a message,i may be able to help
