When your car begins to shake, idle roughly, or lose power while driving, there’s a high chance you’re dealing with Spark Plug Issues. These small components play a major role in engine performance. In 2025, more drivers are realizing that one of the fastest ways to get back lost power and fuel efficiency is to fix Misfiring Engine Fix problems with timely spark plug maintenance.
Spark plugs ignite the air-fuel mixture inside the combustion chamber. Faulty plugs mean incomplete combustion, which can result in misfires, poor mileage, and engine knocking. This guide will walk you through common symptoms, the cost of replacement, and how to fix the issue the right way.
What Causes Spark Plug Issues in 2025?
A spark plug has a limited lifespan and typically needs replacement every 20,000 to 40,000 km. In dusty or high-humidity areas of India, wear and tear occur faster. According to 2025 servicing trends, more vehicles are reporting Spark Plug Issues because of:
-
Irregular servicing and tune-ups
-
Use of low-grade or mismatched fuel
-
Buildup of carbon deposits on the electrode
-
Ignition coil malfunction
-
Oil leakage into the combustion chamber
These factors directly contribute to Misfiring Engine Fix requirements and can lead to more costly engine repairs if ignored.

-
Rough idling or frequent engine stalling
-
Decreased acceleration and power
-
Higher fuel consumption
