My 96 ST is idling low and rough, so I checked the fault codes and got 2:
P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1) P0133 O2 Sensor CKT Slow Response (Bank 1 Sensor 1) Does this mean replace the O2 Sensor, and if so, which one (Cali car)? |

His ECU is MAP based. A vacuum leak won't cause a rough idle. Check your brake light circuit connections and grounds. Could also be a weak battery, wouldn't hurt to have it and the alt tested. --------------------  |

Thanks for the advice. |
