I have a 2004 EB 5.4 2WD with about 187K on the odometer. About 2 weeks ago (Dec. 18) I got a check engine light and when I ran the scan tool I got the codes P0172 and P0175. Generic codes stated that Banks 1 & 2 were running too rich. Ford Specific codes stated ‘Fuel System Too Rich Conditions’. I was able to finally get around to cleaning the MAF Sensor today (Dec. 31). Started the EB up with no problems, no codes, ran until engine got to temp and turned it off. About 20-30 minutes later I went out to run errands with the wife and the check engine light came on. Now I’m coding P2196 & P2198, ‘O2 Sensor Signal Stuck Rich’ for Bank 1 Sensor 1 and Bank 2 Sensor 1.
I’m not getting any other codes indicating a vacuum leak. There are no strange ticks, whistles, or other noises. The engine is not running rough, or worse. Idle has actually gotten better since cleaning off the MAF Sensor. The engine is not stalling or dying. I’ve cleared the new codes for them to come back in about 5 minutes or so.
I have to get smogged soon and register so this is concerning.
Could the new codes be from cleaning the MAF and the computer having to recalibrate?
Could running some Sea Foam Spray through the intake work?
Or is it likely I have to bite the ugly bullet of buying new O2 sensors?
Willing to answer any questions I can to help provide more input if needed to help diagnose the issue at hand.
