Spark plugs play a crucial role in how your engine operates. Without them, your car wouldn’t start, accelerate, or run smoothly. When it's time to replace them, many drivers often wonder: are spark plugs universal, or can I pick up any set from the parts store? Using the wrong type of spark plug will negatively impact your engine’s performance, reduce fuel efficiency, and even cause damage over time. If you plan to replace your spark plugs or just want to better understand your engine, here’s what you need to know.   Spark Plug Fitment Every engine is designed with a specific spark plug size, heat range, and electrode configuration in mind. Engineers carefully choose these specifications to ensure the plug ignites the fuel-air mixture at just the right moment. A plug that’s too long, too short, too hot, or too cold can interfere with that timing or even make physical contact with internal engine parts. The result could be anyth ... read more

If your engine won’t start, runs rough, or keeps stalling without warning, the culprit might be smaller than you think. The crankshaft speed sensor plays a vital role in your car’s ability to run, and when it starts to fail, your engine performance can go downhill fast. Fortunately, with proper diagnostics, this problem is both identifiable and fixable. At B & L Automotive, we’ve seen how a faulty crankshaft sensor can send drivers on a wild goose chase. Here's how we pinpoint the problem and what it takes to repair it.   Why Crankshaft Speed Sensors Matter So Much The crankshaft sensor tracks how fast and in what position your engine’s crankshaft is spinning. This information is essential for the engine control unit (ECU) to properly time ignition and fuel injection. If the sensor’s data is off—or missing entirely—the ECU can’t do its job, and your engine either runs poorly or won’t run at all ... read more

Many drivers don’t think twice about driving through puddles, especially after heavy rain. But water on the road isn’t as harmless as it seems. Even a small puddle can hide deep potholes, and larger pools of water pose serious risks to your engine, brakes, and electrical components. If you’ve ever wondered whether driving through puddles can actually damage your car, the answer is yes—it definitely can.   How Water Affects Your Engine and Air Intake Your engine needs air to function properly, and modern vehicles have low air intakes that can easily suck in water if you’re driving through deep puddles. When water enters the intake, it can cause a condition known as hydrolock, which prevents the engine from running. Unlike air, water can’t be compressed, so when it enters the cylinders, it can cause severe internal damage, including bent connecting rods ... read more

Engines aren’t silent, but they shouldn’t suddenly get louder, rougher, or make unusual noises. If you hear knocking, rattling, hissing, or squealing sounds from under the hood, it could be a sign of an issue that needs immediate attention. Some engine noises stem from minor problems, while others could indicate serious mechanical failures that lead to costly repairs if ignored. Recognizing the cause on time will help you prevent major engine damage and expensive fixes.   Common Causes of Engine Noise Engines make noise naturally, but changes in sound usually mean something is wrong. The type of noise you hear can point to different underlying problems, from simple fixes to severe issues. Exhaust System Leaks and Muffler Damage A louder-than-normal engine often means something is wrong with the exhaust system. This system reduces engine noise, directs exhaust gases safely away, and improves performance. If there’s a leak ... read more

Car electrical issues can be frustrating and difficult to deal with, especially when they interfere with the functionality of your vehicle. Whether it’s a faulty battery, unresponsive lights, or a malfunctioning infotainment system, electrical problems often disrupt your driving experience and demand immediate attention. But how are these issues diagnosed and fixed efficiently?   Why Car Electrical Issues Need Prompt Attention Your car’s electrical system is the backbone of its operations, powering everything from the ignition to the headlights and air conditioning. When something goes wrong, it doesn’t just impact your comfort—it can compromise your safety. Ignoring electrical problems can lead to more significant issues, including complete system failures. This is why a prompt and accurate diagnosis is crucial.   How Do Experts Pinpoint the Problem Diagnosing electrical issues requires specialized tools ... read more
