Why are my new spark plugs misfiring?
Most new spark plugs are packed with plastic or paper sleeves to protect the air gap during shipping. When a sleeve protector is present, the air gap is usually correct. The potential for inadvertently creating a misfire is very real when installing new spark plugs.
Does new spark plugs increase performance?
The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle’s performance. New spark plugs help keep your engine at its peak performance and efficiency levels. Worn or dirty spark plugs require higher voltage to get a strong enough spark to start a vehicle.
Why do you need to replace your spark plugs?
But we’ve got three great reasons why you shouldn’t put off replacing your old spark plugs. Reason 1: New spark plugs help keep your engine at its peak performance and efficiency levels.

What causes an engine to misfire with a worn spark plug?
There may be other reasons why the engine misfires, like a bad ignition coil plug cap or inferior quality fuel. However, a misfire is often the result of at least one worn spark plug. You’ll notice the engine pace falters and then catches back up. You may also hear the engine pop as it loses and regains timing.
Why is my car sputtering after new spark plugs?
It is possible for there to be a vacuum leak, a faulty oxygen sensor, a catalytic converter that is starting to show signs of failure, or even a possible problem in the fuel system. It will be necessary to do some further diagnostics to determine which system is causing the problem, and then figure out which part in that system is the root cause.
Are there still spark plugs in newer cars?
Some later models have an ignition system without a distributor, but they still have traditional spark plug wires. Depending on automaker, those harnesses started to disappear in the late 1990s/early 2000s. Newer vehicles have a coil-on-plug ignition system that eliminates electrical problems caused by worn-out spark plug wires.
