Help! This past weekend I took my 1986 300E to the DMV for inspection and registration and failed as a result of my Idling emissions (both HC and CO) being too high. What might this be a result of? Can it be easily (or inexpensively) corrected? Might it have anything to do with the fact that my engine (and as a result car) wobbles while idling? Is an Idling rate of about 7000 rpm about normal?
Thanks for any help that y'all might have out there....
