i doubt its a cat problem myself. id throw a fuel pressure gauge and see what kind of fp youre getting. also, check your map sensor and make sure the hose is connected and the plug is inserted firmly. if you think (which i doubt) its an o2 sensor problem, you can unplug it and the car will run without it (will throw a CEL though)
