Did you replace the fuel filter ? and check the air filter.

take out the o2 sensor on the drivers side exhaust manifold and drive the thing. not for long, as that hot exhaust could start burning stuff. It won't hurt anything. If it runs better, you have a clogged cat. you will know when you start it, but still drive it up n down the block at least....
