my Toyota RAV4 XA40 (2013-2018) feels sluggish, what could be the cause?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical accidents.

2. Clean or Replace Air Filter

• Remove the air filter housing cover using a socket set.
• Inspect the air filter for dirt; replace if necessary.
• Clean the air filter housing with a damp cloth before reinstalling the new or cleaned filter.

3. Inspect and Clean Throttle Body

• Remove the intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to remove any carbon deposits from the throttle body.
• Reinstall the intake duct and secure all connections.

4. Check Fuel System

• Locate and inspect the fuel pump relay and fuse for continuity.
• If fuel pressure is low, replace the fuel filter.
• If the fuel pump is faulty, replace it according to the manufacturer’s specifications.

5. Inspect Ignition System

• Remove the spark plug wires carefully.
• Check spark plugs for wear and carbon buildup; replace if necessary.
• Test ignition coils with a multimeter to ensure they are within manufacturer specifications.

6. Transmission Fluid Inspection

• Locate the transmission dipstick and remove it.
• Check the fluid level and condition; add or replace fluid as needed.
• If the fluid is burnt or contaminated, consider a transmission fluid change.
