Although not essential for engine operation, intake manifold routing provides improved engine performance and efficiency, particularly at low engine speeds. If the intake manifold runner control fails, the engine can be left without an increase in performance and in some cases even with reduced performance. Typically, a faulty intake manifold runner control will cause several symptoms that can alert the driver to a potential problem and determine if it should be replaced.
