Why is my Suzuki Cultus engine stalling o r having trouble starting with new spark plugs?

If your Suzuki Cultus is stalling o r having trouble starting after replacing the spark plugs, it could be due to several factors:

Incorrect Spark Plug Installation: If the spark plugs were not installed properly, such as being over-tightened o r under-tightened, this can lead to poor contact o r a weak spark, causing the engine to stall o r fail to start.

Wrong Spark Plug Type o r Specification: Installing spark plugs with the wrong specifications, such as the incorrect heat range o r size, can lead to improper combustion and stalling. Always refer to the manufacturer’s recommendation for the right type of spark plugs.

Dirty o r Faulty Spark Plugs: New spark plugs can sometimes be defective o r contaminated with debris, affecting their ability to generate a spark. This could cause the engine to struggle to start o r stall intermittently.

Faulty Ignition System: A malfunctioning ignition coil, spark plug wire, o r control module may prevent the spark plugs from firing correctly, leading to starting issues and stalling.

To resolve the issue, ensure proper installation, use the correct spark plug type, and check the entire ignition system for any faults.
