Hard to start, but when it does start, throttle is wide open.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like it's all or nothing! The symptoms suggest a potential issue with the throttle position sensor (TPS) or the electronic throttle control system (ETC). The wide-open throttle condition upon starting could be caused by a malfunctioning TPS or a problem with the electronic throttle body. Additionally, it's possible that there could be a problem with the engine's fuel delivery system or air intake system contributing to the issue. If you check those and still haven't determined the cause, have a professional mechanic diagnose the problem using diagnostic equipment to pinpoint the exact cause and perform any necessary repairs.
