I'm lost

[flouese]

I've replaced my plugs, coils, MAF, Idle Air control valve and my car will still not run.
It starts right up, idles for a few seconds, then dies a slow death. If I step on the accelerator in an attempt to keep it alive, there is no change. Again, slow death. No CEL codes. The dealer said the AOS needed to be replaced, however, there is no smoke. Would the AOS have anything to do with this issue. Please see "OUCH" thread from last month to see all the issues the dealer said it has. I am lost as what to do next. I want to work on this myself, but I am getting close to where it needs professional help.
