If you own a car, the engine is the heart that keeps you moving. Knowing the basics can save you money and hassle. Below you’ll find straight‑forward advice on the most common engine topics, all pulled from our expert articles.
Bad spark plugs show up as rough idling, sluggish acceleration, or a hard start. Check the plug tip – if it’s black, fouled, or worn, it’s time for a swap. Replacing them usually costs less than a full tune‑up and can boost fuel efficiency.
A weak fuel pump will cause slow cranking, loss of power, or a stalling engine. Listen for a humming noise when you turn the key, then follow our step‑by‑step test to confirm. If the clutch feels sticky or you hear a burning smell, stop driving and get it checked. Ignoring a bad clutch can damage the transmission and leave you stranded.
Other engine‑related concerns, like air filter upgrades, radiator lifespan, and suspension health, also affect performance. An expensive air filter isn’t always worth it – focus on the filter’s flow rating and how it fits your driving style. Radiators typically last 100,000‑150,000 miles; regular coolant flushes keep them from overheating.
When you notice any of these signs, don’t wait for a full breakdown. A quick visual inspection, a simple tool test, or a short drive can reveal the issue. Our guides walk you through the exact steps, so you can decide whether a DIY fix is possible or if you need a professional.
Keeping your engine in shape also means routine maintenance: oil changes every 5‑7k miles, checking belt wear, and topping up fluids. These small habits prevent big problems later and keep your car running efficiently.

Spark plugs are small but crucial components of a vehicle's ignition system, responsible for igniting the fuel-air mixture in the engine cylinders. The number of spark plugs depends on the engine type; most cars today have one spark plug per cylinder. Understanding the correct number for your vehicle can aid in proper maintenance and performance checks. Regular inspection and replacement of spark plugs can optimize fuel efficiency and reduce emissions.
