A Body Stalling at Idle

There seems to be absolutely NO problem with the transmission.........everything feels normal........no shaking, no jitters, no slippage, no locking up apparent when you slow down either........it does not noticeably "drag" the motor down when the rpm's slow down........

I had a GM with overdrive, and it was notorious for dragging and lurching when the lock down wasn't functioning right....this feels nothing like that.

It acts like it's a vacuum leak and won't stay running, but they can find no leaks.

Every time you put the thing in drive, it wants to stall........to keep it going, you have to give it more gas and pump the pedal to get it moving before it stalls.
