P2101 Electrical throttle control motor performance

It coded a P2101 at idle? You have a bad connection check the TPS connections, make sure there are no broken tabs of the throttle body. Here is a BMW with a ETC with a broken tab that went into a limp mode from idle the tabs where broken when funds are limited the use of a zip tie work out well
