Here's why and what potential problems could be causing this:
* Sticking Accelerator: A sticking accelerator is never normal. It could be a mechanical issue with the accelerator cable (if it's a cable-operated system) or a problem with the electronic throttle control system (more likely on a newer vehicle).
* High Idle: This usually indicates a problem with the idle air control system (IAC), the throttle position sensor (TPS), a vacuum leak, or a problem with the engine control module (ECM).
* Check Engine Light: This confirms that there's a detectable fault stored within the vehicle's computer. The code needs to be read using an OBD-II scanner to pinpoint the exact problem.
* Brand New Engine: The fact that the engine is brand new makes this even more concerning. It suggests a manufacturing defect, installation error, or a serious issue with a component related to the throttle control system.
What you should DO:
1. Do NOT drive the car: Continuing to drive with a sticking accelerator is dangerous.
2. Have the vehicle towed to a qualified mechanic or dealership immediately: This is crucial because the problem could cause further damage.
3. Request a complete diagnostic scan: The mechanic needs to retrieve the diagnostic trouble codes (DTCs) from the check engine light to accurately diagnose the issue.
4. Explain the entire situation: Emphasize that the engine is new and the problem started soon after purchase. This might help determine if there is a warranty issue.
Ignoring this could lead to costly repairs or even engine damage. Professional diagnosis is essential to resolve this safely and effectively.
