Bad motor mounts can cause the motor to move excessively, which pulls on the MAP sensor vacumn hose every time you step on the gas pedal. This either weakens the hose so it collapses (causing low vacuum flow) or pulls the vacuum hose that connects the intake manifold to the MAP sensor completely off of the sensor. When the hose is disconnected from the MAP sensor, a full rich condition will result.

I figured it was the cadillac converter. Ive been having an air flow problem for some time now. I replaced all the hoses but still having this issue
As im driving the hose pops off and when i press on the gas it makes a hissing sound
