No I didn't change anything except the injectors to fix this problem. I refuse to throw parts at a problem. I only replace parts that are causing a problem. I work very hard in my shop to diagnose problems and replace only what needs replacing. We have people call and say they want a tune-up. Our first question is WHY? Usually we find that they have a problem and asume a tune-up will fix it. We find the problem, then and only then will we "tune-up" the car if it really needed.
This isn't to say that I don't do regular maintaince. My cars are maintained better than most, I just don't do maintaince to fix a problem. I fix the problem first, then do the maintaince I feel is needed. This applies to my personal cars, and my customers cars.
If you feel you need injectors, then do it AFTER you find the problem.
