1. Distributor Cap and Rotor: Inspect the distributor cap and rotor for any cracks, carbon buildup, or corrosion. Replace them if necessary.
2. Spark Plugs and Wires: Check the spark plugs and wires for any damage, wear, or carbon buildup. Replace them if needed.
3. Ignition Coil: Test the ignition coil to ensure that it is functioning properly. Replace it if necessary.
4. Fuel Pressure: Check the fuel pressure to make sure that the injectors are receiving enough fuel. A weak fuel pump or clogged fuel filter can cause weak fuel pressure.
5. ECU (Engine Control Unit): The ECU is responsible for controlling the ignition timing and fuel injection. If it is malfunctioning, it can cause the engine to misfire or run poorly.
6. Wiring: Check the wiring harness and connectors for any damage or corrosion. Repair or replace any damaged components.
7. Ground Connection: Ensure that the engine has a good ground connection to the chassis. A loose or corroded ground connection can cause electrical issues, including weak spark.
