Could do any number of things. Not start at all. Start and run fine and take random spells of misfiring. Could start and run fine while it's cold then start running worse as it warms up. You can pull the ICM and take it down to AutoZone where they can test if for free. Have them test it several times until it gets warmed up. A lot of times these won't show being bad until they get hot.
