I have what I believe are leaking injectors (green stripe) and am contemplating on having them cleaned and "balanced" vs. replacing them with new injectors (i.e. 009's, etc). Has anyone used this approach? Is balancing of injectors really necessary or worth the $$. I can get my existing green stripes rebuilt for $150 or so compared to $300 for new injectors. Any thoughts/comments are appreciated. Thanks in advance for your help.
