why does my Genesis G70 run rough when accelerating

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to prevent any electrical shorts.

2. Replace Spark Plugs

• Remove the engine cover if applicable.
• Use a socket and ratchet to remove the spark plug wires or coils.
• Using a spark plug socket, carefully unscrew and remove the old spark plugs.
• Inspect the new spark plugs to ensure they are gapped correctly as per manufacturer specifications.
• Install the new spark plugs, tightening them to the manufacturer's torque specification (typically around 13-15 ft-lbs).
• Reattach the spark plug wires or coils.

3. Check and Replace Fuel Filter

• Locate the fuel filter (refer to the service manual for location).
• Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Disconnect the fuel lines from the filter, using appropriate line wrenches to avoid damage.
• Remove the old fuel filter and install the new one, ensuring proper orientation.
• Reconnect the fuel lines and replace the fuel pump fuse.

4. Inspect and Clean Air Filter

• Open the air intake cover to access the air filter.
• Remove the air filter and inspect it for dirt and debris.
• If dirty, replace it with a new air filter.
• Ensure the air intake housing is clean before reassembling.

5. Check Ignition Coils

• Disconnect the ignition coil connectors.
• Using a multimeter, measure the resistance of each ignition coil.
• Replace any ignition coils that are outside the manufacturer’s specified resistance range.
