Need help with DTC's.
My truck has started throwing a couple codes that I need help figuring out a solution. The first one is P0174-bank 2 is too lean. The second one is P0506-IAC Valve duty cycle lower than expected. I also got a code last week saying Bank 1 too Rich but accidentally deleted it before writing down the code. Any idea whats wrong with my truck? It runs fine and I haven't noticed any thing wrong other than those codes popping up on my edge's screen. It only throws these codes when I let the truck idle for about 10 minutes also. They never appear while driving down the road and when they appear my truck is not doing anything weird. All of the guages on the dash look normal. No weird noises. I'm not sure where to begin. Any ideas? My truck has over 106,000 miles on the odometer so I've been expecting some little nitpicking problem to show up at any time. Thanks everyone!
