10 Signs Your Car Needs a Tune-Up


Regular car maintenance ensures your vehicle runs smoothly and safely on the road. A tune-up is an integral part of car maintenance that involves a series of checks and adjustments to improve your car’s performance, fuel efficiency, and reliability. Here are ten signs that your vehicle needs a tune-up at a Toyota service center Dubai.

Poor fuel economy:

If you notice a sudden drop in your car’s fuel efficiency, it may be time for a tune-up. Worn-out spark plugs, clogged fuel injectors, or a dirty air filter can cause a decrease in fuel economy.

Engine misfiring:

If your car engine is misfiring, the engine is not firing correctly or at the right time. Faulty spark plugs, a malfunctioning ignition coil, or a clogged fuel injector can cause this.

Rough idling:

If your car engine runs roughly or shakes while idling, it may need a tune-up. Dirty fuel injectors, a malfunctioning oxygen sensor, or a worn-out spark plug can cause a rough idle.

Difficult starting:

If your car is challenging or takes multiple attempts to start, it may need a tune-up. A weak battery, a faulty starter motor, or a clogged fuel filter can cause this.

Lack of power:

If your car lacks power or struggles to accelerate, it may need a tune-up. A clogged air filter can cause a lack of power, worn-out spark plugs, or a malfunctioning fuel pump.

Engine warning light:

If your car’s engine warning light is on, it may indicate a problem with the engine. Several issues, including a malfunctioning oxygen sensor, a faulty catalytic converter, or a damaged spark plug, can cause this.


If your car is stalling frequently or unexpectedly, it may need a tune-up. Stalling can be caused by a dirty fuel filter, a faulty ignition switch, or a clogged air filter.

Poor performance:

If your car is not performing as well as it used to, it may need a tune-up. Several factors, including a dirty fuel system, worn-out spark plugs, or a clogged air filter, can cause poor performance.

Loud exhaust:

If your car’s exhaust is louder than usual, it may indicate a problem with the exhaust system. A damaged muffler, a cracked exhaust pipe, or a malfunctioning catalytic converter can cause this.


If your car vibrates excessively while driving, it may need a tune-up. Several factors, including worn-out suspension components, faulty tires, or a misaligned wheel, can cause vibrations.
