Default AFR STUCK!

A couple days ago my CEL came on. My AP reads P2177 and P2187. Driving regular speed, the AFR gets stuck at 14.85. Ive been reading around and looks light it might be a bad o2 sensor or an air leak. Any suggestions?

Before you do that. Check your fuses. Specifically the one labeled ENGINE BAR.

I just replaced mine. I had no CEL, but thankfully I play with my AP regularly and noticed my AFR & LTFT were static. (14.8 & 0.2 respectively). Noticed better acceleration and a bump in fuel economy with the repair.

i took apart my tmic and found a 1/4 inch crack in on of my couplers. I used some good ol' duck tape while i wait for my new ones. Still noticed my apr is still at 14.8 when driving. The CEL turned off but not i have a p0401. Read around the forums and every one says to clean out the egr valve?
