Multiple emissions codes and probably wrong calibration.

Haven't had a chance to check more on the fan yet. Been avoiding it really, so I can work on one problem at a time.
To update on the rest. I noticed a small bump in fuel mileage after swapping out the imap and delta p. All the codes were still popping up though. Here's where it gets interesting though. Backstory. I run the same load every day. Amarillo to Dallas to Amarillo. Have since I bought the truck. Fuel at the same place also. They always have prices .40 per gallon cheaper than anywhere else on 287. The full trip takes about all my fuel. I took a different trip yesterday and filled up at a loves instead. A couple of hours later and my engine light went off. Hasn't been back on since. These codes have been popping up for a year now and I've had a lot of work down. Everytime they pop back up an hour or two after leaving the shop. Im gonna change my fuel spot for awhile and see what happens.
