Why does my engine Ping when I Turn on the engine?
As a result, a clogged converter is the most common cause of exhaust back pressure buildup. It will restrict engine airflow causing the engine to run hotter and lose power. Consequently, leading to pinging or knocking. Most of the time, a catalytic converter will clog because, of old age overheating or fuel contamination.
Why does my car make a pinging sound when I accelerate?
However, if the knock sensor is not working, spark timing will not retard when it should. Consequently, you may hear a pinging or rattling sound when accelerating; driving up a hill, or when engine is lugging. By tapping on the engine near the sensor is one way to test it.

The engine is accelerating or lugging under a load. This allows intake vacuum to suck some exhaust in; through the (EGR) valve to dilute the air/fuel mixture slightly. This lowers combustion temperatures and prevents engine spark knock.
What makes the warning chime at intermittent times while driving?
The temperate gauge indicates overheating in stop/go traffic and has stalled a few times when idle. Oil is low could this be it? The first thing to do is to make sure the oil and coolant are filled up to prevent any engine damage. The problem may be caused by low oil but only if engine is oreal low on oil. The coolant…
