Does the camshaft & catalytic converter

p0420,p0455,p0011

I would diagnose the intake valve timing before I would change anything else, and the crankshaft sensor could effect it not the camshaft sensor. Then find the cause of the evap leak, it could as well cause the code for the convertor. Have you been religious about your oil changes and the right grade of oil. The valve timing is off and the cause needs to be found or it will stay in fail safe mode.
