Your Alfa Romeo flashing check-engine light is an emergency that requires immediate attention. Driving with blinking lights may result in significant damage to the engine. You end up spending more on Alfa Romeo services or replacement costs, depending on the extent of the damages. Reduce these costs by understanding the potential causes of flashing check-engine lights and their remedies.
1. Faulty Spark Plug
If your check-engine light doesn't stop blinking, faulty spark plugs might be the culprit. The spark plug is a vital component for efficient engine operation. If it's defective, it can cause the engine to misfire. Consequently, the check-engine lights keep turning on and off.
Other signs of a malfunctioning spark plug include:
High exhaust emissions
Problem starting your car
Visit an auto repair shop as soon as you notice any of the above signs for inspection. Your Alfa Romeo service center specialists will examine the condition of the spark plugs to overrule them as the cause of flashing engine check lights. If the spark plugs are faulty, the experts will repair or replace them immediately before they cause more problems.
2. Bad Ignition Coils
The ignition coil is liable for powering the spark plugs. If the ignition coil malfunctions, it won't send enough power to the spark plugs. Consequently, the spark plugs cannot create adequate spark to light the air and fuel mixture in the engine. This issue causes the engine to misfire, and in return, the check-engine lights start blinking.
Besides flashing check-engine lights, faulty ignition coils may manifest in the following ways:
Engine not starting
Odd sounds (coughing and spluttering noises
If not fixed sooner, a faulty ignition coil may cause severe damage to the catalytic converter and cylinders, resulting in an expensive repair.
You can protect ignition coils from failing through scheduled engine maintenance. The ignition coils go hand in hand with spark plugs. Therefore, save the coils from falling by regularly changing the spark plug wires. Most importantly, take your vehicle to a reliable Alfa Romeo service center to fix flashing check-engine lights immediately after you notice the problem.
The specialist will inspect the ignition coils and replace them if necessary. The car repair professional will also test the vehicle for other underlying problems that could make the lights misbehave.
If you notice flashing check-engine lights, then you should act fast to avoid costly repairs.
