Probably not your problem but when I removed and disconnected stuff to install my Steeda short throw shifter I failed to fully ingage one of the wiring connections when putting everything back together under the hood. Well when I tried to start the car I got a suprise. It didn't take to long to figure out but I had a major panic attack for a few minutes. Maybe in your case something came loose. Hope it's an easy fix. Keep us posted.
