Hrmm... Took it into Southside Toyota yesterday and for the first time I was unimpressed with their service. Apparently they can't hook the ECU up to their diagnosing machine thing because of the engine mods (ie - The headers). Apparently, 'some' of my O2 sensors are put on incorrectly (1 before and 1 after the Catalytic Converter). However, from the description Supatouring has told me, it appears that the ONLY 2 O2 sensors are placed correctly. But, according to the Service Advisor this will 'screw up' their machine. Sounds like they had no idea what to do and they just fobbed me off, the dude even suggested some performance shop. No engine fix + no brake install = Andrew being annoyed @ Southside Toyota
