I reviewed some of your post and man you have problems running out your ears.
Starting with the cat replacement and similaters.
Also a Bnayor said that low vacume is not right.
Throwing more cats at it is not going to help you.
No offernse but It sounds like it is getting over your head. You have had some good answers to all of your questions but you are not following threw on the you keep jumping from one thing to another.
In your best interest I would advise you to find a good REPAIR SHOP AND LET THEM HAVE AT IT.
Here is some tips on finding one.
Good Luck MT
Check around Ask around
Word of mouth.
Family friends coworkers neighbors business people and delivery people.
Mailmen and parcel delivery people get around and notice a lot of stuff.
Even a good parts house knows what shops are good and not good.
Chamber of commerce and better business bureau and city hall.
If you find a good referral to a repair shop go look them over and talk to them.
Look for a clean looking busy place with nice people running it.
Ask a few questions and ask about their qualifications and training.
Not all places have trained tech/mechanics.
If they do not find a place that does.
Even all dealers do not have all trained techs/mechanics.
Also if you go to a dealer repair shop.
Tip on going to the dealer
Ask that only a factory certified gasoline engine performance specialist work on your car.
Not all dealerships are concerned with how repairs are dispatched, and not all dealership techs bother to take advantage of the training offered by factory (the vast majority of which is paid training). If the dealer is uncooperative, ask for your money back and call around for a dealer that will accommodate you.

MT2500, seconded, no one is going to fix this deal over the internet!!!

A/T - Shift/Driveability Concerns/SES Lamp ON

Bulletin No.: 04-07-30-013A
Date: January 25, 2005
INFORMATION
Subject:
Automatic Transmission Shift, Engine Driveability Concerns or Service Engine Soon (SES) Light On as a Result of the Use of an Excessively/Over-Oiled Aftermarket, Reusable Air Filter
Models:
2005 and Prior GM Cars and Light Duty Trucks
2005 and Prior Saturn Models
Supercede:
This bulletin is being revised to add additional model years and to clarify warranty coverage. Please discard Corporate Bulletin Number 04-07-30-013 (Section 07 - Transmission/Transaxle).

The use of an excessively/over-oiled aftermarket, reusable air filter may result in:
^Service Engine Soon (SES) Light On
^Transmission shift concerns, slipping and damaged clutch(es) or band(s)
^Engine driveability concerns, poor acceleration from a stop, limited engine RPM range
The oil that is used on these air filter elements may be transferred onto the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a result, the Grams per Second (GPS) signal from the MAF may be low and any or all of the concerns listed above may occur.
When servicing a vehicle with any of these concerns, be sure to check for the presence of an aftermarket reusable, excessively/over-oiled air filter. The MAF, GPS reading should be compared to a like vehicle with an OEM air box and filter under the same driving conditions to verify the concern.
The use of an aftermarket reusable air filter DOES NOT void the vehicle's warranty.
If an aftermarket reusable air filter is used, technicians should inspect the MAF sensor element and the air induction hose for contamination of oil prior to making warranty repairs.
Transmission or engine driveability concerns (related to the MAF sensor being contaminated with oil) that are the result of the use of an aftermarket reusable, excessively/over-oiled air filter are not considered to be warrantable repair items.

Thanks for the edit. It is a Lot better now.
