Amazing... Finally someone with my problems as well, but mine is only when it heats up.

Powers1 has been back and fourth we my but still cannot find the issue.

I have had ever sensor checked, the Turbo, the Vacuums, the MAF (even with my MAF disconnected, I got no dash errors, and no change in revs or running rough, etc like you). Also had the Engine Management software updated/reflashed without an difference.

I thought my problem occured after an oil change, but 90% proven it didnt (from various people).

If you get yours fixed, keep us informed as it will probably be my problem too.

You can PM me with questions if you want as I have done some much testing..
