98 civic throwing 4 codes
P0420 - Catalyst system efficiency below threshold bank 1
P0430 - "" "" bank 2
P0133 - A/F sensor 1 response malfunction
P0153 - AF sensor 21 slow reponse
98 civic ex. Sometimes the car runs fine and other times it starts to sputter and acts like its running out of gas. I've had bad O2 sensors before but the only effect was terrible gas mileage. Are all these codes playing off one another? If I replace the front O2 sensor will most/all these codes go away?
