What is your question?
2004 Cadillac SRX V8- check engine light on and misfires continually at Idle, hesitates on acceleration and jerks when manual transmision shifts at low speeds. I changed spark plugs and all 4 Camshaft Position Sensors sense that code and code P0300 was detected but car still does the same thing after the change. Also now I have a rotten egg smell from exhaust pipe which the Catylitic Converter may have failed. What can be causing the misfire? I understand that it would make no sense replacing the cats until the misfire has been corrected.

You might want to check all the O2sensors, they have caused ne trouble in the past. I believe there are 4 in total and are in the exhaust system. A dealer can tell you where they are located, and if you have the desire you can replace them yourself, but use WD40 or a penetrating rust solvant as these sensors have been heated & cooled a million times. Also do the job after the exhausts have cooled down.
