I'm new here, I'd really like to get some info about my car's catalytic converter system! I recently replaced the 2 converters built into the exhaust manifold, are there any more on my model? I also replaced the 3 O2 sensors as well. My car was hesitating and just bogging out when attempting to pull a hill. The Lexus dealer did a diagnostic on it, and said that I had a restricted converter and needed to replace the sensors, still my car runs like sh*t! However, if I simply unplug the O2 sensors, it runs quite well! Any suggestions would be greatly appreciated! I know theres another O2 sensor right below the passenger flowboard on the exhaust, I havent replaced it yet, where does it connect as well, I'd like to unplug it too!
