How do I fix misfire and CPS faults


Topic starter

I have a 2008 Saturn Vue XE 2.4L 4 Cyl, brought to mechanic, PO300, PO340, PO341. They replaced 2 Cam Position Sensors, 2 Camshaft Position Accuator Solenoids OEM Dealer. After replacement: Code 300, 340, 341 still showing. Check Engine Light Still On. Driven car 300 miles since repair. They said take car to dealer and have ECM reprogrammed. Can you please help me as far as what to do.

Thank you,
