O.K. s the latest.

I disconnected the vacuum line to the booster and plugged it, idle remained at 900 RPM.

When I applied the brakes, NO decrease in RPM, so, I'm guessing that the booster is a problem, but when I shifted into DRIVE, the RPM dropped to about 575 RPM. about where it was previously, with the booster connected.

I'm at a loss, someone mentioned torque converter, can that affect idle?
