The car idles very rough and is sometimes unresponsive when the gas pedal is pushed. I am getting a P0155 and 1152 code when this happens. I have changed the pcv valve and the air filter.
scan says p1152 lack of ho2s21 switch sensor indicator rich and p0155 upstream heated O2 censor heater circuit fault bank 2
Replacing the O2 sensors will fix the idle? The codes only show up after I have a problem with the idle?
