Here's why you should take your car to a mechanic:
* Knocking: Engine knocking can be caused by several issues, including:
* Detonation: This happens when the fuel ignites prematurely, causing a knocking or rattling sound. It can be caused by poor fuel quality, a faulty knock sensor, or problems with the ignition timing.
* Low oil pressure: This can cause engine parts to wear down and knock.
* Mechanical problems: Worn bearings, a damaged piston, or other internal engine issues can cause knocking.
* High Idle: A high idle (3500 RPM) is also a serious problem. It could be caused by:
* Vacuum leak: A leak in the intake manifold can cause excess air to enter the engine, increasing idle speed.
* Faulty throttle position sensor: This sensor tells the engine control unit (ECU) the throttle position, and a faulty sensor can cause the engine to idle high.
* Faulty idle air control valve: This valve regulates the amount of air entering the engine at idle, and a faulty valve can lead to high idle speed.
What to do:
1. Take your Kia Spectra to a qualified mechanic. They can diagnose the problem and provide you with the best solution.
2. Describe the symptoms clearly. Let the mechanic know when the knocking started, how it sounds, and if you've noticed any other unusual behaviors.
3. Be prepared for possible solutions. Depending on the cause, the repair could be simple (like replacing a faulty sensor) or more complex (like engine repair).
Remember, neglecting engine problems can lead to further damage and expensive repairs. Don't try to fix it yourself unless you have the expertise and equipment.
