HI Mr. Hamilton
I can think of no less then 6 things off the top of head that might turn you CEL on an none of them are injectors. Codes need to be read an then checked for possible cause. Find out more before you plunk down big cash for injectors either at the dealer or find a good independent. Ask people who drive them where they get theres FIXED, then call the BBB and see what they have to say about them. Good luck.
