CHECK ENGINE LIGHT KEEPS COMING ON----O2 Sensor codes

[DUVALINCOLN]

LS Family,

I have a 2004 Lincoln LS with 143,000 miles V8. For the past couple of weeks I have been having some hesitation in acceleration, rough start in the morning, and check engine light keeps coming on.

So far I have replaced fuel filter and all the spark plug & coils replaced.

There check engine light came on with code 0133 and I replaced all four O2 sensors. The check engine light this morning with codes 0153, 0133. I erased the codes to see if it returns but what else could it possible be if light comes back on?????

Thanks

Be sure you have the sensors in the correct position. double check. make sure you have the correct sensors for the car. double check

Sorry to be THAT guy, but did you try the stuff people were recommending in your other thread? Cleaning the MAF and intake related equipment? Did you check the wires to the sensor?

If I were you: I would check the wiring on the sensors, check the MAF, the intake, the air plumbing, check the fuel injectors. If all of that stuff checks out it may be the cat itself, if you were running on bad coils for a long time.
