SAVE YOURSELF THE HEADACHE AND LET A MECHANIC DO THIS ONE. CAUSE IF YOU DON'T KNOW WHERE THE PLUGS ARE YOU SHOULD NOT TRY TO CHANGE THEM!
Please post returned codes , after spark plug replacement.
Your spark plugs are located under the ignition wire on both sides of the engine...they should be fairly easy to replace.
