Comment 2
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. -

I recently purchase the car. Do you recommend that I get an oil change prior to going the shop?? Or should I wait until I receive the diagnosis from them? -
Comment 4
Sorry I got busy; Make sure the oil is fresh, it is used for the actuation of the valve. -
Comment 5
Ok I will do that. I haven't change since purchasing the vehicle a week ago. -
