Ford Explorer Sport 2001 sensor failure

Good afternoon. Today I took out the sensor 1 of Bank 1 and was very full of carbon, had the gray cable and a white peeled and glued together. The other two oxygen sensors were in better condition and all of them had been cleaned in the same way two months ago. Replace sensor 1 of Bank 1, the car feels without strength at the time of starting and then takes strength. For tomorrow I am going to clean ultrasound injectors to see how it behaves.

Comrade If you have a very strong smell in the Salaida de los Escapes, the problem is that the Catalix
Zadores are very covered. of fuel. Like all these sensors, they work in the entresi the scanner send you several codes but it does not tell you anything specific to do not checked physically all these components. [

The oxygen sensor, left before the catalyst does not work, or the cables are damaged, Quitalo check it and wash it; spark plugs 1 and 3 are not working (the first and last on the left side) this can be due to damaged cables, damaged spark plugs or your coil no longer works.

If the cables are new, check that they have +/- 5K OHMS.
Check spark plug calibration.
If everything is ok, your coil already gave them.

The flat sensor does not work, it is driving your computer crazy because it presents rich and poor mixtures.

A symptom is that the troca has no strength, and it must be spending a lot of gasoline.
