Hello I'm Neal and I am here to help resolve your issue. If I cannot help I will opt out and refer your question to another expert.

It sounds like a vacuum leak or a partially plugged catalytic converter. I would double check for vacuum leaks and exhaust leaks. I assume those are the only codes?

Well it dont have any exhaust leaks and it haves 2 catalytic converters i was gonna take the 02 sensors off to see if it idles different but i cant get the sensors off cause there is a piece of metal that is in the way of the sensor so i dont know what else to do
Expert:  Neal replied 4 years ago.
Removing the sensors will not really give a good result. You really need to get a diagnostic where the can check them based on the sensor readings.
