Hey guys so i just picked up a 1988 mustang
5.0 and the guy i got it from just put a new battery in the day i got it and he put the terminals on wrong he put the positive on the negative and the negative on the positive and the car wouldn't start i had to bump start it. do you think there is any major damage done to it? and the car was running rough it wouldn't idle it would just shut off. any tips??
