one of my hose (upper)was crack and i replace it but for one reason or another after i put
the new hose and use the turbo on the car you can feel it but at the same time is like
something is holding up the motor?

ANY IDEA?

 

Maybe another hose has a hole in it as well or the other one is collapsing under pressure.

 

I would think that if one is cracked the rest are not far behind it might be a good time to replace all so the vacuum gremlins do not appear
