everytime i drive on the highway for about 15 minutes my CEL comes on and it reads: P2009 - Intake manifold runner control circut low bank 1a. I dont really experience anything other than bad mgs (i would usually get about 28 mpg but on recent fill up i barely got 24) anyone have a solution?

It seems like every time it gets warm again the msp throws another cel and takes all my saved summer cash.
 
Huh sounds like the VTCS or VICS is malfunctioning. I haven't pulled that code before. Hopefully, someone else will chime in, but it could be a bad solenoid on one of the actuators.
