CEL Problem Persists Depsite Repairs

[thom4782]

I have a 2001 S. Several months ago, the CEL light came on with codes P0410 and P1411.

So far, I've done the following: 1) 90K service. 2) replace inoperable solenoid in passenger bank variocam, 2) replaced all valves and vacuum lines in secondary air ssystem, 3) replaced the air oil separator and its breahter hoses. The computer suggests the MAF and O2 sensors are operating within proper ranges. The air pump seems to work ok too.

Still, after each repair, the CEL popped back on. It always happens when the car has just started. After driving for a couple of minutes and less than a mile, I'll look down and see the CEL.

Anybody have any suggestions where to look next. I'd appreciate any suggestions.

Thanks
