OK, how about that belt you tightened, did the problem occur shortly after that? I suspect a possible problem with the item on the belt you tightened. First, was it the alternator or the power steering? Any noise when idling and giving it gas to stay idling? You may have compounded a problem with the alternator (guessing the alternator belt was tightened) having a bearing that is going out. Tightening the belt puts a lot of pressure on the bearing and it stumbles along at higher rpm but lower rpm it drags the engine down.
Back-up lights, there is a fuse for that, if not that check the wire to the transmission for the switch and it not loose or a bad wire the switch itself could have failed.
