I put a strut tower brace on my 94 mkiv today, and in order to do this i had to remove a black box device that was covering the driverside strut tower, while doing so i droped my wrench and it hit one of the batter terminals on my optima battery and this caused the Fan Fuse to blow (I think) but i got everything back together and when i put the car into drive it has a vibration and when it is in neutral it doesn't at all, in park the same vibration but not as bad. Can someone help me figure this out, this is my first mkiv and i am getting frustrated.
