How do I tell if I have a burnt spark plug?
I’ve recently been having engine issues with my car. My friend had similar issues with their car and said it ended up being burnt-out spark plugs. How do I tell if I have a burnt spark plug?

Any change in your engine’s performance can be frustrating—and expensive, depending on the issue! If you have a burnt spark plug, you might experience any of the following issues with your vehicle:
- Trouble starting the car
- Rough engine idling
- Engine misfiring
- Lower gas mileage
Of course, these issues can also indicate other problems with your engine. It’s always wise to have your vehicle inspected by a
mechanic
if you’re having engine trouble.A mechanic can replace any burnt-out spark plugs in a few hours, and repairs are pretty cheap. The average cost is between $65 and $150 depending on the make and model of your vehicle.
