Spark Plug Refresh: Get Your Old Motor Humming Again!
> Spark plugs are the little blighters that spark the air/fuel mix in your engine. They slowly degrade, causing misfires, less power, and you'll be pouring more gas in. Especially noticeable in older legends like the Toyota Liteace and Mazda 323.
Spotting Dodgy Spark Plugs:
• Engine's misfiring, idling rough, or hesitating.
• Fuel bills suddenly higher than a kite.
• Engine's a pain to start.
• That pesky check engine light's on.
• Acceleration feels like you're towing a boat anchor.

Worn spark plugs mean your emissions will be up. Get them sorted or you'll be gutted when you fail your WOF.
DIY or Workshop?
Difficulty: 6/10
Time Needed: 1-2 hours

🛠️ Bob's "Get It Done Right" Companion Checklist
• Safety First, Mates!: Sparks plugs are easy, but engines get hot! Wait until it's cooled down before you start fiddling. Wear Nitrile Gloves to keep your hands clean.
• Cleanliness Counts: Before removing the old plugs, blast around the spark plug holes with an air compressor or a can of Brake Cleaner to stop muck falling into the cylinders.
• Protection Pays: A tiny dab of anti-seize grease on the new plug threads makes life easier next time around.
• Lube It Up (Lightly): Apply a tiny smear of dielectric grease inside the spark plug boot to keep moisture out and ensure a good connection.
