My car is losing torque. I am suspecting a vaccuum leak in my intake manifold but I could be wrong. Has this happened to you??? What should I do to fix it??? Thanks for your inputs in advance

 

If there is a vacuum leak in your intakemanifold, the idle should be all funny (up and down). But I dont think a vacuum leak will have any effect on the torque. I could be wrong. if you do have a vacuum leak then check all the gaskets and hoses or gaps/holes.
