Answer 1

HI there,

This code is for the intake manifold runner stuck open. The intake manifold runner is under the intake and opens when you accelerate. If it's stuck open it's usually either caused by the runner itself being full of carbon and varnish at which point it can be cleaned so it moves, or the actuator for the runner has stopped working. Without proper diagnoses there really it's any way to know the costs.
