I recently got a check engine light after about a month of noticing a slight decrease in MPG. After a day or so, the check engine light went out on its own. I just got a bluetooth OBDII reader, and the Torque app is reading a P0172 error code, "System too rich (Bank 1)". Some troubleshooting I researched is to see what the truck is reading the barometric pressure as, to see if it's the MAF sensor. Problem is, Torque doesn't seem to be reporting a baro. The gauge is just blank. Is this normal, or indicative of bad part? Any experience with this code and trouble-shooting techniques would be much appreciated. Thanks
