Sounds like BS to me. So your saying O2 Sensors never fail?

The Oxy sensors are NEVER the problem. It's the intake doing it.
Go to a Ford dealer and tell the parts guy what your problem is and they have a kit.
It's quite a job and not for the novice. Also, if you're going to do it, remove the deck where the wipers are for better access. Taking my time it took about 4 hours.
Did it last year and it runs perfect and no more codes. |
