  1. Keep getting P0133 code

    Hi! Actually, I haven't done anything related to performance mods yet. The only thing installed is a muffler/resonator keeping the original exhaust piping. Sent from my iPhone using Tapatalk
  2. Keep getting P0133 code

    Hi everyone. I've been struggling with the P0133 code "Oxygen Sensor Circuit Slow Response" for a couple of months already. It seems that it could be anything causing it. I ride a 2009 Mitsubishi Lancer ES Sport package (USDM) stock with some 172,000 miles on it. I checked for any leaks at the exhaust, got nothing. Changed the Sensor 1 Bank 1 O2 sensor (before cat), still got the same code. Changed spark plugs, went for a throttle body maintenance, nothing. All maintenance to date. Same code still there. It would help me a lot to know what can be causing this code to keep showing up. Thanks in advance! Sent from my iPhone using Tapatalk
