Idle RPM goes down when wheel is turned
When in idle, my tach shows (and I can hear) the rpm drops almost all the way to the bottom when I turn the wheel all the way to the either side. It does this only when the wheel is turned to the maximum. As soon as I release the wheen from maximum turned position, rpm comes back to normal (around 750 rpm). Does anyone here have the same experience? How did you diagnose this problem? Thanks in advance, you guys are the best!!!
PS: I have an 89 RX7 Vert, N/A, mostly stock (k&n air filter)....

The Air Supply Valve is supposed to open when you turn the steering wheel. That's supposed to makeup for the load you put on the engine. You do know where the Air Supply VAlve is.
EDIT: That's for a tubo car. On a non turbo I'd suspect the Air Bypass Valve is suppossed to do that function. Just guessing. I don't have a series five car. I'd suggest reading the FUEL seciton of the online, free fsm for your series car.

The two most likely causes are a problem with the BAC valve (disconnected or clogged) or a problem with the PS pump pressure switch (failed switch, wiring damage).
