For P1124/P1126 the air/fuel mixture is so lean the DME is at its enrichment limit.
Possible causes are intake system leaking (which could be an AOS leaking); fuel pressure too low; fuel injectors contaminated; fuel supply low or fuel not getting to the fuel pump.
Of the above, fuel supply/pressure problems are generally rare, while almost every owner (it seems) has had an AOS go bad, so I'd suspect the AOS first.
Sincerely,
Macster.
