A buddy of mine as a 02 lb7 with 150,000 miles on it, and his injectors took a crap on him. My question is whats the warranty on these injectors? I thought it was 200,000 miles. The dealer told him it was 200,000 miles or 7 years. Does that sound rite. And his 7 years was up about 3 months ago and will not fix them under warranty.
