Question Fuel trim question???
I have a 2000 z28 with cam, headers, and the usual, and when I am looking at my Fuel Trim LT and ST both say that its 25% on the right side and just about perfect on the other side what would cause one side to run soooo lean?? Any Help would be great!!

try swapping them from side to side and see if the problem switches from one bank to the other. If so, then it is a bad o2.
