The car I'm working on keeps needing to have the throttle body relearned.
Pull the etcs fuse for 15min or so, then go driving and it sorts itself out and works fine. Couple days later the idle speed is all over the place again. Replaced with a used throttle body, but it does the same thing. Relearn without issue, but needs to be done every few days? Any input would be greatly appreciated.
Thanks in advance - Ian

Yes I have. Did that with the first one prior to replacing, and the used 1 prior to installing
