Similarly, will AutoZone help change spark plugs?
A gapping gauge tool is available from AutoZone. A small amount of anti-seize maybe used on most but not all spark plug brands and types. Check the box or the plug manufacture. Install each new spark plug, being careful not to cross-thread and damage the spark plug and cylinder head threads.
Similarly, can I replace my own spark plugs? Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor. You can use the same old tune-up tools (ratchet, spark plug socket and gap gauge). You should use a torque wrench to tighten the plugs. But there's a way to get around that if you don't have one.
Similarly one may ask, how much does it cost to change spark plugs?
Spark plugs are incredibly inexpensive, often costing less than ten dollars apiece. Now you may need to replace several at once, but it still won't cost very much. The typical amount you will pay for spark plugs is between $16-$100, while for labor on a spark plug replacement you can expect to pay around $40-$150.
How can you tell if your spark plugs are bad?
Symptoms of bad spark plugs can include:
- Reduced gas mileage.
- Lack of acceleration.
- Hard starts.
- Engine misfires.
- Rough idling.
