P0172 2014 3.5L Ecoboost?
Changed plugs. Long term fuel trim on both banks is going to -25 at idle. Both banks go normal when rpm's increase.
My OBD is showing catalyst = not passed, O2 sensor = not passed, O2 sensor heater = not passed.
Any suggestions? Much appreciated!
Where is MAF in this truck? I'd like to clean/test it.
I found the 3 MAP's and replaced one of them that tested bad.
