1zz Throttle body review/tips - Toyota Yaris Forums

mattymo · 12-17-2014, 09:07 PM

All, tb swap is kicking my butt. I've tried everything...chip swap, dial in good idle while warm after battery cycle, but i still get P0505 idle control system code. It also jerks sometimes letting on and off the throttle. Does anyone think i should adjust other stop screw inside the tb? This looks like it sets how far back the valve can close. It looks like the ecu can actually fully shut the valve the way it's set now. Does the ecu actually do this? Any suggestions? Preeshiate it. Car runs great under this mod when it's cooperating, but flakes into this code.
