Hi - today we needed to change spark plug and ignition coil on the engine. Temporailiy disconnected some wires (MAS flow sensor and removed the hose from the throttle body. We were able to solve the misfire, but landed this code next (p2009). We noticed upon 1st turn on, the lever that controls the intake runner was moving back and forth on its own, making the engine rev up and down. We shut the car off and re-installed the sensors making sure they were tight and also removed and replaced the hose into the throttle body. The lever stopped swaying back and forth and the engine was smooth again but code P2009 re-appeared. Any suggestions?
