soo i finally got the MAP sensor and as soon as i put it in the engine vibrations became better, sound better, so i logged in to se what is happening, A/F ratio is nice and stable 14.7, BUT both of my O2 second sensors after CATs are both 2.49volts, after i reach engine temp above 180 all ok, until my bank 1 cat heats up and O2 sensor 2 starts working giving ~1.28v while the bank 2 O2 sensor 2 still gives me 2.49v, my A/F ratio goes immediately to 15.09 on both banks.
why do those sensors control my A/F???? arent they only there for EPA reasons??
that bank 2 O2 sensor is new and the car has 44k miles, am sure my cat is done for. il get back when i replace it.
