How much is enough ??
The main task for the MAP sensor is to input load information into the
ECU. In general, high vacuum corresponds to a closed throttle, requiring
less fuel, and low vacuum indicates an open throttle, requiring more fuel
from the injectors.

A disconnected hose means the same thing to the MAP as WOT. The ECU
will increase the injector duration, although I'm not sure how it handles
the fact that the TPS is indicating a closed throttle Confused

If you have low pressure in the fuel rail, opening the injectors for longer
will let a bit more fuel into the engine. This probably helps your idle.

I'd still be looking to confirm what pressure/flow you have to the rail.
