My problem is that it seems like no matter what I do I cannot get my car to idle at a normal AFR. It idles at about 17-1. Ive tried changing the bottom row of cells to 10 and all it does it make it run at 10-1 for a few minutes then it will jump back to 17-1 it seems like the stock computer compensates for what ever number I change. So yesterday it was idle lean so I put 10 in for the bottom cells it went rich. Then I slowly changed the bottom cells to 4.5 and it was idling great so figured I would be sure that its going to stay like this so I gave it some gas and it went back and at sat at 14.5-1. Then burnt the map to xede and it when back up to 17-1. I have a few codes and I'm thinking maybe they could be causing this problem. one is too lean idle and no second o2 sensor. so I'm open for any suggestions. This is the map I'm running.
