Updated coil packs were installed when the new motor was installed. Timing belt is brand new, new spark plugs. I haven't checked the coil packs yet as I haven't had time to mess with it, but when the car misses it acts like you cut the switch off for about a full second then it picks back up... didn't really seem like a coil pack issue to me, then again I've never messed with these cars. Car ran excellent until the day I pulled the steering wheel off to fix the headlight switch, battery stayed unhooked for a full day as I kept getting distracted while working on it, the next day as soon as it fired it wasn't running right.
