Pressure Noise Under Engine
I here a noise under the engine when I am driving. It sounds like it is more towards the passenger side almost like if it were releasing air pressure. When hte noise goes off I can feel the car jolt and change the car's performance. I am not sure if it is a decrease or increase in power becasue as soon as the revs go down I accelerate and the power feels stronger. I have never heard this before, but then again I just got the CV Joints replaced along with all my engine gaskets.
Any suggestions as to what this might be?

It's common for those pulley bearing to go. Gl..
