My 1999 Toyota Tacoma recently started being a bit sluggish so I decided it was time for tune-up. I replaced my fuel filter, plugs, cables and one ignition coil that had oxidization/corrosion on terminal. After reconnecting everything my truck runs terribly (way worse than before the tune-up) and has slight back fire, any ideas?
