Engine
Estimated Time
2-4 hours

Safety Warnings

  • ⚠Disconnect the battery before working on electrical systems.
  • ⚠Relieve fuel pressure before disconnecting fuel lines to prevent spills.

Symptoms

  • •Check engine light illuminated
  • •Rough idle or engine shaking
  • •Decreased acceleration or power
  • •Poor fuel economy
  • •Possible engine stalling
  • •Increased emissions

Diagnostic Steps

  1. 1Scan for error codes using an OBD-II scanner to confirm P0301 and check for any additional codes.
  2. 2Inspect the spark plug and ignition coil for cylinder 1 for wear or damage.
  3. 3Check the fuel injector for cylinder 1 for proper operation and fuel delivery.
  4. 4Perform a compression test on cylinder 1 to rule out mechanical issues.
  5. 5Inspect vacuum lines and intake manifold for leaks that could affect cylinder performance.
  6. 6Check the engine and transmission mounts for wear, as they can contribute to perceived misfires.

Solution

Solution

1. Preparation

  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool before beginning work.

2. Replace Spark Plug and Ignition Coil

  1. Remove Engine Cover (if applicable)

    • Use a socket set to remove any bolts securing the engine cover.
    • Lift off the cover carefully and set aside.

  2. Access Cylinder 1 Components

    • Locate the ignition coil and spark plug for cylinder 1 (typically at the front of the engine).

  3. Remove Ignition Coil

    • Unplug the electrical connector from the ignition coil.
    • Remove the bolt securing the ignition coil using a socket wrench.
    • Gently pull the ignition coil out of the spark plug well.

  4. Replace Spark Plug

    • Use a spark plug socket to remove the old spark plug.
    • Inspect the old spark plug for wear and carbon buildup.
    • Install the new spark plug, tightening it to the manufacturer’s specified torque (typically around 15-20 lb-ft).
    • Reinstall the ignition coil onto the new spark plug and secure it with the bolt.
    • Reconnect the electrical connector to the ignition coil.

3. Replace Fuel Injector (if necessary)

  1. Remove Fuel Rail

    • Relieve the fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
    • Disconnect fuel lines from the fuel rail using appropriate tools.
    • Remove the bolts securing the fuel rail and lift it off, taking care not to damage any components.

  2. Replace Injector

    • Remove the old fuel injector from the rail.
    • Install the new fuel injector, ensuring it seats properly.
    • Reassemble the fuel rail and reconnect fuel lines, ensuring no leaks.

4. Reassemble and Test

  • Reinstall any components that were removed, including the engine cover.
  • Reconnect the negative battery terminal.
  • Start the engine and check for smooth operation.

Verification

After completing the repair, verify that the issue has been resolved:

  • ✓Test the affected component to ensure it functions correctly
  • ✓Check for any error codes or warning lights
