Other thing...watch the lights dim when coming off throttle.

Yes, spoiler light on this car stays on until the car moves a few feet and then goes off. Always been that way. My 03 doesn't do that.

I'll get the o2 stuff in the morning. Do you know which values they are?

clogged cat could be the issue. Going to see if I can make adapters this week to fit the pressure gauge/vac gauge. If I can will see what pressure is before & after the 1st cat that is part of the header. I would just loosen the bolts between the header & muffler but those are ones I can't get off unless I'm going to cut them off.
Sorry, i misread the post earlier, I thought it was 18 at idle I haven't gotten to watch any videos (everyone else asleep in the house) but the voltage and light dimming that youre describing is no bueno. Have you checked your alternator and battery? Im not sure how that would play in here but it's hard to tell with electronically controlled fuel injectors.

To measure the exhaust pressure, don't try to separate the joints. There are 18mm bung adapters to hook a pressure gauge to. The cheap way to do it would actually be just remove a sensor and leave them bung open - if that changes performance then you know you have a backpressure issue.

I didn't see if you responded earlier but what's the deal with your aos? Monty is right, the aos can actually kill your oil pressure if the failure is complete. All this could go together - bad aos, poor idle vacuum, intake flooded with oil, intake gasket degraded, fouled injectors causing lean running (? Maybe?), fouled spark plugs, clogged cats.
