P2006Powertrain
Intake manifold runner control stuck closed (bank 1)
Where to start
The intake manifold flaps are stuck closed. Almost always soot: the flaps sit in the intake and clog up, especially on diesels and direct-injection engines. Removing and cleaning solves it; replacing the manifold is rarely needed. The symptom is dull acceleration low down while the top end feels normal.
A code is not a diagnosis. It says which check failed, not which part to replace. Clearing it without repair only means the car will report it again in a few trips.

How the app helps
CarScan reads this code from your car through an OBD-II adapter, shows whether it is active now or only stored, names the module that reported it, and puts it into a plain-text report for your mechanic.
