Cats clog up from carbon and contamenents , I dont have a catylitic converter on my grand am its got a midstream resonator glass pack (free flow nothing in it) and a reversed blue bottle for a muffler and the way I drive theres no way its carboned up. Thanks for the ideas tho.
The slight hesitation happens only when the tranny is at normal operating temperatures or hotter , maybe that helps a bit more in givin you guys an idea of what could be happening with it.
