My name is Julia I have a 99 ford f-350 with a power strok diesel, I have just recently had to have the # 8 Injector replaced twice and I am still having the same miss and rough idel, no power problem as I did before I replaced the # 8 injector. My truck only has 95,000 miles on it I should not be having this problem. I have been told that it is not covered under warranty because it is over 5 years old. I have put $3,000 into trying to fix this problem and it seems that there is no way to really fix this. I am a very loayal ford owner but if ford is not willing to help fix this problem I will become a Chevy owner real soon. Please help with this problem. I love my truck and it has been the best truck I have owned up until now. This is a vehicle that was purchased for me by my father before he passed away, so it also contains sentimental value there. I know this really has nothing to do with the problem. Thank you, Julie
