O2, CAT or something else? Bogging down 700

If you have a vacuum gauge you can check for exhaust/cat blockage. Connect the gauge to the intake manifold after the throttle body. With the engine idleing and the ac off you should get 15-17 inches or so. Run the rpms up to around 2500 and the vacuum should not change much. Any drop of 3 or more can be a good sign of exhaust restriction.
