Have had to replace the O2 sensors, thermostat, and plugs and wires. it still gives a code for the catalyst and something aboutvapor(fuel) code? I was told that they would reset with driving. How do I reset these?

the cat code indicates an effiency issue. it most likely has to be replaced. rarely is the o2 sensor at fault with a cat code. if you drove your car with missfires for a long time, it most likely damaged the cat to the point it needs to be replaced. the code will go away when the issue is resolved. the tech repairing the car will re set it.

Thanks for your help. By cat, I am assuming that this is the catalytic converter?
