I have a 2002 LB7 stock; now over 7 years old and out of warranty, 56K miles and well cared for, it would appear that I now have one or more leaking injectors and little hope that GM will cover repairs. Does any one know if new GM injectors have been redesigned to correct this problem or if an aftermarket source of improved injectors is available, more reliable not more horsepower? Also if anyone knows how to get GM to cover repairs that would be helpful too. I think I will be doing the work so if any other suggestions come to mind that would be great as well. Thanks Mark.

All injectors with the date codes of 08 and later should have the newest revisions. Get only Bosch remans not some off the wall shop so called reman. There are plenty of [laces to get them from not all have good prices though.
