I just replaced my injector nozzles with new bosio models and now when I start the car it is rough. When it warms up the car runs better, but it seems like it has a hint of a miss. Did I put together an injector wrong? This is the only mod I performed and it ran fine prior to this. Also the problem is really evident when the car is floored and about to shift into 4th gear. It really stumbles and almost does not want to shift. It is not a vacuum problem though. As I have fixed that problem and it shifts excellent before that.
