My ignition switch,starter solenoid,battery went out a month ago....I replaced those parts and the mustang is firing up with no problem but is running rough and fouling plugs, Im not driving it or anything but this is how its currently acting while it sits still.....The stang is a daily driver and before this i have had no problems with it....I am curious to whether the computer may have been fried in a certain component when the electrical ignition switch went out???....Any help would be greatly appreciated!!!!
