After car has been sitting for more than an hour or two it cranks with a rough idle then smooths out normally. It does not miss thru driving and runs good overall.I had new plugs and wires and ignition control module put in 6 months ago.I do not hear any vacuum leaks. Maybe a new air filter will help or may go get some bosch plus 4 plugs to see if it helps. Will a diagnostic check show anything?
