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.

    The vehicle was running rough and the gas mileage was in the gutter (9 miles per gallon). The vehicle was also stalling out when it hit a bump. The dealer stated that the Camshaft Sensor was bad. The oil was just changed 500 miles ago. This vehicle gets an oil change every 4 months, it only travels under 5,000 miles a year.
