What is it?
Intake manifold runner control is an engine management component that is found on newer intake manifold designs. It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners. The unit will open and close the butterfly valves in order to provide maximum manifold pressure and flow at all engine speeds.

While an intake manifold runner is not necessary for engine operation, it does provide the engine with increased performance and efficiency, particularly at low engine speeds. When it fails, it can leave the engine without the increased performance, and in some cases even reduce performance. Usually a faulty IMRC will produce a few symptoms that can alert the driver of a potential issue.

Symptoms of a Bad or Failing Intake Manifold Runner Control:Difficulty starting the engine;Engine misfires and decrease in power, acceleration, and fuel economy;Check Engine Light comes on.

How to Replace an Intake Manifold Runner Control?
Locate the IMRC.

You can find it on your engine. It may be necessary to remove a few plastic covers before you see it. Often, it's bolted directly to the top of the intake manifold or at one end or the other. Sometimes it is bolted in a remote location, like the valve cover, and will use a cable connection to the intake fla
