I had a buddies truck in the shop last week that was an 03 that had a knocking, excessive black smoke and a obvious miss. He bought it used with 60,000 and now it has 120,000 miles. The IDS said #3,5,7 missfires and a turbo boost code with no CEL ON AT ALL. We put 4 new injectors in and long story short didnt fix it. #5 was fixed but 3 and 7 were no change. It was blowing oil out the dipstick tube so we decieded to let the dealership get into this guys pockets, and he needs a new motor. $10,000 dollars for a new motor. Buy a late model if you can, but **** happens with these things. I know cause i bought a new 03 and it was in the shop every other week for 11 months. Dont put all your faith in the oasis reports. This guy had one too. Not wanting to scare you but just a warning. Tim
