P2008 - Intake Manifold Runner Control (IMRC) Circuit Open (Bank 1). The IMRC'S (intake manifold runner control) are what make an intake both a long runner and short runner intake. For upper rpm power or wide open throttle the butterflies open, for around town they stay closed. They have a sensor(s) and either vacuum motors or electric motors. The IMRC'S are located between the upper intake plenum and lower intake manifold. In your case the butterflies may be stuck open causing a lean condition and a miss or the engine to die. If I recall, this will also cause the fuel pump control to go a little crazy. I think you have a vacuum leak to the IRMC (bank one) or a bad electrical connection (corrosion) causing your problem.
