Car Shaking Problems

My son was in the back seat and admitted that he had farted. That was the cause.

Ford Pinto.

When the system is active this is normal due to the braking system being applied to a spinning wheel or a wheel that in under or over steering.

What exactly does an oxygen sensor do? The answer is in the name; An oxygen sensor measures the amount of unburned oxygen in the exhaust system left after combustion in the engine's cylinders. Based on the amount of Oxygen present, the sensor generates a voltage which is read by the engine's fuel management system. Too much residual O2 in the exhaust, and the car's computer releases more fuel for the next combustion cycle; too little O2, and the opposite happens. This balancing act happens many times every second to maintain the optimal fuel to air ratio of 14.7 : 1. This ratio has been found to produce the most efficient combustion, and therefore, the most power, and best fuel economy.The oxygen sensor helps maintain your vehicles harmful emissions. It does not restrict the exhaust flow in any way. Oxygen sensors are typically mounted in front of your catalytic converter/converters and muffler/mufflers so that the oxygen sensor can read the amount of oxygen in the exhaust. From there, a signal is sent to the computer that makes the proper air/fuel mix, or at least makes adjustments to correct the air/fuel mix. If not taken care of in proper time, your oxygen sensor can cause other other problems like premature failure of your catalytic converter, increasing the total you will spend with the next repair. With the prices of gas as high as they are, keeping your oxygen sensor up to date, or replacing it when it's time, will save you hundreds of dollars each year just in fuel costs. The typical time to replace an oxygen sensor for vehicles made from the late mid 1970s to about 1990 is about every 30,000 to 45,000 miles. For the newer makes and models, get your oxygen sensor checked about every 80,000 to 100,000 miles. If your check engine light comes on, have your mechanic check the oxygen sensors when you take your car in.

The section width of a tire refers to the measurement of the tire's width from sidewall to sidewall when properly inflated and not mounted on a rim. It is typically expressed in millimeters and is the first number in a tire's size designation (e.g., 205 in 205/55R16). This measurement is crucial for ensuring proper fitment on a vehicle and can affect handling, stability, and overall performance.

A tire is generally considered acceptable if its out-of-round condition is within 0.125 inches (1/8 inch) for passenger vehicles and up to 0.25 inches for larger tires, such as those on trucks. However, even slight out-of-roundness can lead to vibrations and uneven wear, so it's best to address any noticeable issues promptly. Regular tire inspections can help identify this problem before it affects performance. Always consult the tire manufacturer's specifications for the most accurate guidelines.

To replace the rear spark plugs in a 2003 Ford Taurus, first, ensure the engine is cool and disconnect the negative battery terminal. Remove any necessary components to access the rear spark plugs, such as the intake manifold or engine cover, if applicable. Use a spark plug socket and ratchet to carefully unscrew the old spark plugs, then insert the new plugs, tightening them to the manufacturer's specifications. Finally, reconnect any components you removed and the battery terminal.

The firing order for a Lincoln Mark LT with a 5.4L V8 engine is 1-3-7-2-6-5-4-8. This firing order is typical for Ford's modular V8 engines and ensures smooth operation and balanced power delivery. It is essential for maintaining engine performance and efficiency during operation.

A grinding and popping sound from the front left wheel could indicate several issues, such as worn brake pads, a damaged wheel bearing, or a problem with the suspension components. If the brake pads are worn down, they may grind against the rotor, while a failing wheel bearing can create a popping noise as it loses stability. Additionally, loose or damaged suspension parts, like struts or control arms, can cause similar sounds when driving. It's essential to have the vehicle inspected by a mechanic to diagnose and address the issue promptly.

Your Audi may start to shake while driving due to several potential issues, including unbalanced or misaligned wheels, worn-out tires, or suspension problems. Brake issues, such as warped rotors, can also cause vibrations, especially when braking. Additionally, engine or transmission problems may lead to shaking, particularly at certain speeds. It's best to have a professional mechanic diagnose the issue to ensure safe driving.
