Why does my diesel engine shake while idling?
November 3, 2022
Much higher compression, so the amount of energy transfer between the rotation of the flywheel and the charge in the compressing cylinder is higher. That means the variation in the rate of rotation of the engine is higher, and the back-reaction torque from the compression strokes tends to shake the whole engine.

They hold the brake pads and press them against the rotors when you step on the brake pedal, helping your car slow down or stop. Over time, calipers can wear out or get stuck due to dirt, rust, or leaks. When this happens, your car might pull to one side, your brake pads may wear unevenly, or you could notice a burning smell after driving. A stuck caliper can put extra stress on your brakes and tires, leading to bigger and more expensive problems. If your brakes don’t feel right, it’s best to have them checked before the issue gets worse. At David’s Automotive Repair, we’ll make sure your brakes are working properly.

Over time, both wear down from the friction created every time you press the brake pedal. Brake pads are designed to press against the rotors, creating the stopping power needed to slow your car. When pads wear too thin, they can’t grip properly, leading to longer stopping distances and potential damage to the rotors. Rotors, the metal discs that the pads press against, also wear down and can become damaged and grooved, causing vibrations or squealing noises when braking. If you hear squeaking, grinding, or feel vibrations when stopping, it may be time to have your brake system checked. Ignoring these warning signs can lead to more expensive repairs and put your safety at risk. At David’s Automotive Repair, we inspect your brakes to ensure everything is working as it should. If you’re noticing any issues, give us a call at 972-625-1836 to schedule a reservation.

One common cause is low coolant levels. Your engine needs coolant to stay at the right temperature, and if there’s a leak or not enough fluid, it can overheat. A failing thermostat might also be to blame. If it gets stuck, it can prevent coolant from flowing properly. Other possible causes include a faulty water pump, a clogged radiator, or a broken cooling fan, all of which help regulate engine temperature. If your temperature gauge keeps rising, it’s best to have your car checked right away. Driving with an overheating engine can lead to costly repairs or even a breakdown. At David’s Automotive Repair, we can diagnose the problem and get your cooling system working properly again. Call us at 972-625-1836 to schedule a reservation today!

The light can come on for many reasons, from a loose gas cap to a more serious engine issue. If the light is steady, your car may still be safe to drive, but you should have it checked soon. If it’s flashing, it could mean a more urgent problem that needs immediate attention. In either case, it’s best to avoid long drives until you know what’s wrong. Getting your car checked as soon as possible can prevent small problems from turning into costly repairs. At David’s Automotive Repair, we can perform testing and analysis to find out what’s causing your check engine light to come on. Don’t wait until it leads to bigger issues—call us at 972-625-1836 to schedule a reservation today!

The exhaust system helps control engine noise. So when something goes wrong, you might hear loud rumbling, hissing, or rattling sounds. A common cause is a leak in the exhaust system. If there’s a hole or crack in the pipes, muffler, or catalytic converter, it can make your car much noisier. A damaged muffler won’t be able to quiet the engine’s sound like it should. Loose or broken parts in the exhaust system can also create rattling noises, especially when driving over bumps. In some cases, a failing catalytic converter can cause a loud roar or even a rattling sound if parts inside it have broken apart. Ignoring a loud exhaust can lead to bigger problems. This includes reduced engine performance and harmful fumes leaking into the cabin. If your car is making unusual noises, it’s best to have it checked as soon as possible. At David’s Automotive Repair, we can inspect your exhaust system and get your car running smoothly again. Call us at 972-625-1836 to schedule a reservation today!

A clogged air filter can make the engine work harder, using more gas than necessary. Low tire pressure can also waste fuel by creating extra resistance while driving. Problems with the fuel system, like dirty fuel injectors, can keep the engine from burning gas efficiently. Even a bad oxygen sensor can throw off the fuel mixture, causing your car to use more gas than it needs. Driving habits also play a role—quick acceleration and hard braking can use up fuel faster than steady driving. If your car is burning more gas than usual, it’s a good idea to get it checked out. Fixing small issues now can save you money at the pump and help your car run better. At David’s Automotive Repair, we can find out what’s causing the problem and get your fuel efficiency back on track. Call us at 972-625-1836 to schedule a reservation today!

One of the biggest reasons this happens is a problem with the suspension system, which helps keep your tires in the right position on the road. When the suspension is out of alignment, some parts of the tires may wear out faster than others. Worn-out shocks or struts can make the tires bounce too much, causing uneven wear. If any suspension parts are loose or damaged, they can change how weight is spread across the tires. This leads to bald spots or rough edges. Even low tire pressure can make the problem worse if the suspension isn’t working right. Taking care of your suspension helps your tires last longer and keeps your ride smooth. If you notice uneven tire wear, it’s a good idea to have it checked before it leads to bigger problems. At David’s Automotive Repair, we can inspect your suspension and tires to keep you safe on the road. Call us at 972-625-1836 to schedule a reservation today!

If your heater is blowing cold air, it could be a sign that something isn’t working properly under the hood. One common cause is low coolant levels. Your car’s heating system relies on hot engine coolant to warm the air before it enters the cabin. If there isn’t enough coolant, the system can’t do its job. A malfunctioning thermostat could also be the culprit. If it’s stuck open, the engine may not reach the right temperature to heat the air. Another possibility is a clogged heater core, which can prevent warm coolant from flowing where it’s needed. Sometimes, air pockets in the cooling system or a faulty blend door can also keep warm air from reaching your vents. If your heater isn’t working as it should, it’s best to have it checked by a professional. Ignoring the problem could lead to bigger issues down the road. At David’s Automotive Repair, our team can diagnose the issue and get your heater working again so you can stay comfortable on the road. Give us a call at 972-625-1836 to schedule a reservation today!
