i got this 94 mustang back in the summer of 2002. it's been idling rough ever since i had it. i once read that cleaning the fuel injectors will work, so when i was about to do it, the michanic told me something else. he took out a timing light, and hooked it up to the coil pack, or whatever. he said how i'm gonna need a new one, cause some cylinders are misfiring. keep in mind this michanic isn't ripping me off, cause this is a non profit shop. so i guess i need a new coil pack. has anyone had this problem, or know where i can get a coil pack? i've looked around this forum for a bit, but couldn't find anything, plus i'm active duty military, so my spare time is very limited. can anyone help me out?
