A guy came to me today and was telling me how he was doing the injectors on his 02 cummins But loosened the back screw on the injector hold downs. He said after he did it he was told not to loosen those. And asked me how to re set them. And i dont have an answer for him. and now im curious. I have the service manual from Chrysler and haven't found an answer.so if any one knows please let me know. Thank you
