Hello all,
Recently picked up a 99 suburban with 281,000k or 170,000 miles. The truck runs fine, and gets about 15.2mpg(us). Looking at the injectors they appear to be originals but dont know for sure.
Aside from removing and testing them, how do you know when its time for new ones, and what could I expect to gain from this rather spendy maintenance issue if I did replace them?
