Did you say you changed 1 fuel injector, or was that a typo. You have to change all 6 at one time (unless only one was not working properly). Anyway, it seems that the fule/air ration is mixed up now (the amount of fuel coming to the engine is changed with the new properly working injectors). There is a little hole on top of the air-filter cover (the big black cover), it leads a screwdriver to a little screw that's used to adjust the air/fuel ratio. You can play with it right or left (move it extremely slowly to the right or the left) to adjust the ratio. It's best done by a machine that properly reads the ratio and accordingly the technician will adjust it moving the screw clockwise or counter-clockwise to reach the right ratio. I hope this will help, good luck.
