Help please! My car keeps failing emissions, the need new O2 sensors and them a year later i have not put them on yet im about to. But recently i noticed that my truck was not running the way it used to it is shaking real bad and seems like it wants to stall out. Do i need a new Cat converter? Also i was told that i have a leaky gasket on the manafold? Is the shaking from my CAT CON? Or is it something else.

The cat could be a problem. Have you lost power? If not, then the cat is okay. As far as an intake manifold leaking, that would cause a rough idle. Are you sure that all O2 sensors are bad? Has the check engine light come on?
