Failing spark plugs often exhibit specific symptoms that can affect your Khyber’s engine performance. A misfire o r rough idle is a common indication that the spark plugs are no longer functioning properly.

Signs of Spark Plug Failure:

Engine misfires o r rough idling, especially when accelerating o r under load

Loss of power o r hesitation during acceleration

Decreased fuel economy

Difficulty starting the engine o r starting with a rough idle

Increased exhaust emissions blue o r black smoke

What You Should Do:

Inspect each spark plug for wear, cracks, o r heavy carbon buildup.

Replace spark plugs if they are damaged o r show significant signs of wear.

Regular spark plug maintenance is key, and if they’ve been in use for more than 30,000 km, it’s time to replace them.
