I know this thread is old but I have a question and something to add.

For those who have stalling issues on decel, you need a better engine management system.
I'm having this problem with my atmospheric and stock ECU(haven't really changed anything significantly from stock SR), and I know the SR originally came with a recirc because it's identified as such on the SR service manuel (mine was actually still in the clip when I got it, unhooked and disabled of course).
would this problem not be logical with a stock ECU as it was tuned (from the factory) assuming there was a recirc?
also comment: $3 expanding freeze plug (one of those HELP! pieces from any auto parts store) will fit in the intake hole easily, then as you torque it will expand to plug that hole perfectly. clean and more important, reliable. mine came with a rubber cap held with a hose clam...until it dry rotted and split.
