Suddenly, it all makes sense :)

Interesting Smile

If no hot water is getting to the valve, your idle is going
to stay high. High idle and a closed idle switch in the TPS means you
get this...

- engine speed goes high with closed throttle
- ECU says car is decelerating, and initiates fuel cut
- engine speed drops until ECU turns injectors back on
- engine speed goes high with closed throttle
- ECU says... bla... bla... and over and over again Smile

Pulling the MAP sensor tube takes away one of the three required
elements for fuel cut to occur... there must be high vacuum. Likewise,
disconnecting the TPS takes away the closed throttle signal. Blocking
the air bypass port with your finger takes away the high idle... simple !!!!

So there you are... you have contributed to solving a mystery that has
had me wondering for a long time. Clear the blockage from that water
tube and you should be able to put your AAV back in place, and it will
work fine.

Cheers and good luck... jondee86
