The variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the Check Engine Light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern.
