my Honda Accord Eleventh Generation (2023-present) shakes when I start the engine what's wrong

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to ensure safety during the inspection and repair.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Multimeter
• Screwdrivers
• Engine oil (if necessary for engine mount lubrication)

2. Inspect Engine Mounts

• Raise the vehicle securely on jack stands.
• Visually inspect all engine mounts for cracks, wear, or separation.
• Use a pry bar to gently test the stability of the mounts.
• If damaged, proceed to replace the engine mounts.

3. Check Ignition System

• Remove the engine cover (if applicable) to access the ignition components.
• Inspect spark plugs for wear, deposits, or damage; replace if necessary.
• Test the ignition coils with a multimeter to ensure they are functioning properly.
• Replace any faulty coils.

4. Examine Fuel System

• Locate the fuel pressure test port and attach a fuel pressure gauge.
• Start the engine and monitor pressure; it should meet manufacturer specifications.
• If pressure is low, check the fuel filter and pump for clogs or failures; replace as needed.

5. Inspect Air Intake System

• Check the air filter for cleanliness; replace if dirty.
• Inspect the intake hoses for cracks or looseness; replace or repair as necessary.
• Ensure that the throttle body is clean and free of carbon build-up.

6. Assess Exhaust System

• Visually inspect the exhaust system for any visible leaks or damage.
• If equipped, check the catalytic converter for blockages or overheating.
• Replace any damaged components to restore proper exhaust flow.
