Hey guys help me out. I am usually in the 95 tech area but this one is for my brother. 97 Mustang GT 4.6 2v. I disconnected his battery to re-wire a lightbar and reconnected the battery and now the car starts up idles okay, but smokes and when I put the car in Drive or Reverse it dies. I thought that once you disconnect the battery you have to reset the computer by letting it idle. But for how long I don't know. I don't know the procedure for re-connecting the battery and resetting the car so that it can run again. Any help would be greatly appreciated. The car ran fine before I disconnected the battery. What do you guys think?
