why does my Toyota RAV4 have poor acceleration after 60 mph

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Clean Throttle Body

• Remove the air intake duct by loosening the clamps with a socket set.
• Detach the throttle body from the intake manifold by removing the mounting bolts.
• Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon deposits.
• Reinstall the throttle body and reconnect the air intake duct.

3. Check and Replace Fuel Filter

• Locate the fuel filter; typically found along the fuel line.
• Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Disconnect fuel lines from the filter using a line wrench and remove the filter.
• Install the new fuel filter in the correct orientation, ensuring all connections are secure.

4. Transmission Fluid Check and Replacement

• Locate the transmission dipstick and check fluid level with the engine running.
• If low, add the appropriate type of transmission fluid as specified in the owner's manual.
• If fluid is dirty or burnt, drain the transmission fluid using a drain pan, replace the filter, and refill with new fluid.

5. Inspect and Replace Spark Plugs

• Remove the ignition coil cover if applicable to access the spark plugs.
• Use a socket and ratchet to remove each spark plug.
• Inspect the old spark plugs for wear; replace them with new ones if necessary.
• Reinstall the ignition coils and cover.
