I don't know if this applies to the revving in neutral, but it sounds like you have clogged cats. They can cause problems like that very easily.

You're going to remove the cats? Don't forget about 5th/6th port activation .

bad signal to your secondary injectors.

-check injector clip on secondary injectors(the ones you can see on the manifold)

-bad resistor pack(86-88)

-bad wiring harness(broken contact from injector to resistor pack to computer)

-bad secondary injectors

-bad computer(not likely)

Its most likely the injector clip, probably lost metal retainer clip and worked its way off, and is sometimes making contact.
