Possible causes- Intake manifold air control valve position sensor circuit open circuit
- Intake manifold air control valve position sensor circuit poor electrical connection
- Faulty intake manifold air control valve position sensor
- Intake manifold air control flap too tight or sticking
Spoke to the mechanic today and Ive now been told the valve that activates the flap on the manifold is broken...but doesnt know if the valve is sold separately?
Can this valve be brought? Otherwise its a whole new manifold
