While replacing the muffler intake air control (small square squishy cube that looks like sugar cube) it was inadvertently dropped into the throttle body and into the intake manifold. It must have bounced towards the back and I cannot find it and remove. Is this something that I need to absolutely get out by removing the entire intake manifold or is it okay to leave it in there. Trying to avoid spending $700 but will do it if necessary. Thanks for any help.
