4G93/BYD F3/Junjie Idle Motor BT59603 with Spring Idle Control Valve

For BYD F3 and Junjie with 4G93 engines, attention: this idle speed motor (OEM: 4G93-F3) features a spring design and is a direct OEM replacement with broad compatibility. It stabilizes idle speed by precisely controlling the intake bypass passage; resolves engine shudder in neutral or park, as well as surges or stalling at idle. Symptoms like high idle on cold start, vibration when hot, or slow idle speed decay indicate aging; replacement is advised.
