Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Address Air Filter Restrictions

• Sub-steps:
  1. Locate the air filter housing.
  2. Remove the screws or clamps securing the housing.
  3. Take out the air filter and inspect it for dirt and clogs.
  4. If dirty, replace with a new air filter (ensure it's the correct part for your model).
  5. Reassemble the air filter housing.

3. Check and Replace Fuel Filter (if necessary)

• Sub-steps:
  1. Locate the fuel filter; refer to the service manual for specific location.
  2. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
  3. Disconnect the fuel lines from the filter (use caution as fuel may spill).
  4. Remove the old fuel filter and install the new filter in the correct orientation.
  5. Reconnect fuel lines and ensure they are secure.

4. Clean Throttle Body

• Sub-steps:
  1. Remove the intake duct leading to the throttle body.
  2. Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
  3. Ensure no cleaner residue remains before reassembling.
  4. Reattach the intake duct securely.

5. Inspect Exhaust System

• Sub-steps:
  1. Check for visible damage or blockages in the exhaust system.
  2. Use a back pressure gauge to test for excessive back pressure in the exhaust.
  3. If a clogged catalytic converter is suspected, replace it with a new one.
