2. Address Fuel System Issues

  1. Check Fuel Filter:

    • Remove the fuel filter and inspect for clogs.
    • Replace the filter if necessary.
    • Tools Required: Fuel line disconnect tool, wrench set.

  2. Inspect Fuel Pump:

    • Use a fuel pressure gauge to check pump operation.
    • If pressure is below specifications, replace the fuel pump.
    • Tools Required: Fuel pressure gauge.
3. Clean or Replace Idle Air Control Valve

  1. Remove the IAC Valve:

    • Locate the IAC valve, typically mounted on the throttle body.
    • Unplug the electrical connector and remove the mounting screws.

  2. Clean or Replace:

    • Clean the valve with throttle body cleaner, or replace if damaged.
    • Reinstall the valve with new gaskets if necessary.
    • Tools Required: Screwdriver, throttle body cleaner.
4. Check Spark Plugs and Ignition Coils

  1. Remove Spark Plugs:

    • Use a socket wrench to remove the spark plugs.
