Auto Diagnosis Mesa, AZ

Have you ever gone to the doctor for a checkup because something just doesn’t seem right? Sometimes the vehicle you drive needs the same thing. The best way to find out what is causing problems with your car is to bring it in for a checkup. Our trained technicians know what to look for when performing an auto repair diagnosis and how to find solutions. The more the information you can give the technician about your cars symptoms, the quicker they can make a correct auto diagnosis.

Some symptoms you might notice:

• Hard to start, cranks awhile before the engine starts
• Hesitation during acceleration
• Difficulty shifting
• Do you experience shaking in the steering wheel,
• Brakes hard, braking slower than it used to
• Other items that you have noticed

Other things to consider

Take note of when the issues happen, is the issue only first thing in the morning or does it also happen after you have been driving the car? Does the issue get worse when driving up or down hills? This kind of information will be helpful for the technician to make a proper evaluation for your cars symptoms to determine the repairs needed.

Most late model cars have computers that sense what is going on in the engine to maintain its optimum performance. Our technicians will use specialized testing equipment that provides codes suggesting what the problem might be so they can make the right evaluation. These electronic codes only point to an area of concern, for example not enough oxygen could indicate a faulty sensor or a blocked filter or some other issue. This is where our technical experience comes in to determine the actual solution. The ACE certified technician will then do a visual examination and determine what is causing the issues with your vehicle. That way they can give you an informed repair solution.

Top 10 frequently asked questions (FAQ) for engine auto diagnosis:

Why is my check engine light on?

The check engine light can illuminate for various reasons, ranging from minor issues like a loose gas cap to more serious problems like a malfunctioning sensor or engine misfire. It’s essential to have it diagnosed promptly to prevent further damage.

What does it mean if my engine is making a knocking noise?

A knocking noise could indicate several issues, including low oil levels, worn-out engine bearings, or ignition problems. Ignoring this sound could lead to severe engine damage, so it’s crucial to have it inspected by a mechanic. 

Why is my engine overheating?

Engine overheating can result from issues such as a faulty thermostat, low coolant levels, a malfunctioning radiator fan, or a water pump failure. Continuing to operate an overheating engine can cause significant damage, so it’s important to address the issue promptly.

What does it mean if my engine is misfiring?

Engine misfires can be caused by several factors, including faulty spark plugs, ignition coils, fuel injectors, or a vacuum leak. Misfires can lead to reduced engine performance, increased emissions, and potential damage to the catalytic converter.

Why is my car’s fuel efficiency decreasing?

Decreased fuel efficiency can be attributed to various factors, such as dirty air filters, worn-out spark plugs, improper tire pressure, dragging brakes, or fuel system issues. Regular maintenance and addressing underlying issues can help improve fuel economy.

What causes rough idling in my vehicle?

Rough idling can stem from issues like dirty fuel injectors, a clogged air filter, vacuum leaks, faulty spark plugs, or problems with the idle control valve. Ignoring rough idling can lead to more significant engine problems over time.

Why is there smoke coming from my exhaust?

Smoke from the exhaust can indicate different issues depending on its color. White smoke may indicate coolant entering the combustion chamber, blue smoke may suggest burning oil, and black smoke might indicate a vibrant fuel mixture. Each requires attention from a mechanic.

What should I do if my engine stalls?

Engine stalling can result from various issues, including a faulty ignition system, fuel delivery problems, or engine sensors malfunctioning. If your engine stalls, safely pull over, turn off the ignition, and have the vehicle towed to a qualified mechanic for diagnosis and repair.

How can I tell if my engine has a timing belt or timing chain?

Most modern vehicles use timing chains, which are more durable and require less frequent replacement than timing belts. However, some older vehicles and certain models still utilize timing belts. Consult your vehicle’s manual or a mechanic to determine which your vehicle has and when it needs maintenance.

Why is my engine emitting strange odors?

Unusual smells from the engine compartment can indicate issues such as oil or coolant leaks, burning rubber or plastic components, or overheating brakes. Identifying and addressing these odors promptly can prevent further damage and ensure safe operation of your vehicle.
