Question
i have a 1992 chevy Corsica 3.1 v6 well i just gotten a new catalytic converter and o2 sensors and my car has been running weird when i turn the steering wheel all the way to the left it makes a vibrating noise and vibrates it also does this randomly while driving and makes a weirder noise when we drive out of a dip

Answer
You may actually be feeling too much of engine vibrations. If the cat is touching the floor or a motor mount isnt tight it will feel like its running rough when it isn't.  You should go back to the shop and tell them it doesnt feel like it did when they did the work.  Be nice to them and just say you want it looked at.  A pleasant attitude will do wonders. We hate to hear "ever since" but shit happens.
