Oxygen sensors
I have a 2008 F150XLT with the 5.4L V8.Have been having a lot of trouble with it stalling and backfiring. Have recently changed spark plugs,mass air flow sensor,and cleaned out throttle body and changed air filter. Ran good for about 2 weeks but now it's doing the same. Engine light has come on so took it to get checked and computer says it's the oxygen sensors. Now I've got two questions on this, one,how do you know if it's the back or front sensors and also can these sensors be taken out and cleaned like you would do to spark plugs????

There are no codes that say "it's the oxygen sensors".
Oxygen sensors cannot cause the driveability symptoms you have described. However, other faults can cause those symptoms and the oxygen sensors are there to read the fault condition. Inexperienced guys often misinterpret the fault codes to implicate the messengers instead of understanding how the system works.
Post the EXACT fault codes (Pxxxx) for troubleshooting assistance.

Thanks for your help guys, turns out it wasn't the O2 sensors after all!! Was a defective air filter!!! DAMN thing was torn ,cone on top came off and that was the reason for the stalling and bogging out!!! Went out and got a Spectre performance air filter and truck is running like a champ!!!

Countless hours spent tuning Ford modular motors, and equally as many dyno pulls have proven to me that 02's certainly should be changed more often as mentioned. You be proactive your way, and I will be proactive my way.
