My husband saw the code. The auto guy websites said a leak between the air filter and the air throttle body (there is an air intake boot with 5 connection points). Sure enough the boot was broken along the valley of a seam. one trip to autozone and $64 later, the problem was fixed. don't forget to pull the lead off of your battery to reset the engine code.
