Check the vacuum line behind the throttle body. On mine the gasket was crack and it was sucking air. Find the PVC valve on the front valve cover and follow the vacuum line back to the throttle body. The line "T"s and there is a Gasket where the line enters the intake. I found a replacement line in the "Help" products at Advance Auto.
