When spark plugs become old or dirty, they struggle to produce a strong and consistent spark, causing the engine to misfire and run unevenly at idle.

2. Reduced Fuel Efficiency

Fuel efficiency is a crucial aspect of any vehicle, and spark plugs play a significant role in optimizing it. When spark plugs are worn out, they can misfire or fail to ignite the air-fuel mixture efficiently. This results in incomplete combustion, leading to decreased fuel efficiency and increased fuel consumption.

3. Difficulty Starting the Engine

A failing spark plug can make it challenging to start your 2012 Toyota Camry. If you find yourself struggling to start the engine or experiencing delayed ignition, it may indicate that one or more spark plugs are not functioning correctly. This issue can be particularly noticeable in colder weather conditions.

4. Engine Misfires

Engine misfires occur when the spark plugs fail to ignite the air-fuel mixture properly. This can result in a loss of power, rough running, and even the illumination of the check engine light.

If you notice any unusual or inconsistent engine behavior, such as hesitation or jerking during acceleration, it is crucial to have your spark plugs checked.

5. Poor Acceleration and Power Loss

Worn-out spark plugs can also lead to a noticeable decrease in acceleration and overall engine power. If you find that your 2012 Toyota Camry is sluggish or struggling to pick up speed, it may be due to inefficient combustion caused by faulty spark plugs. Addressing this issue promptly can restore your vehicle’s performance.

6. Increased Emissions

Spark plugs that are not functioning optimally can contribute to increased emissions from your vehicle. Incomplete combustion caused by worn-out spark plugs can result in higher levels of unburned fuel and pollutants being released into the atmosphere.

If you fail an emissions test or notice excessive smoke from your exhaust, it may be time to replace your spark plugs.

When to Replace Spark Plugs

Regular spark plug maintenance is crucial to keep your 2012 Toyota Camry running smoothly. While the exact replacement interval can vary depending on factors such as driving conditions and the type of spark plugs installed, a general guideline is to replace them every 30,000 to 50,000 miles or every 3 to 5 years.
