The fifth generation Accords have a recall for emissions problems. Have your Honda dealer, who should have told you this, to check, using the car's serial number, to see if your car has been through this recall service. If the car has under 150,000 miles, you are due the free emissions work, plugs, wires, distributor and an oil change, all free. Also, Honda Corporation will refund you any money you paid for emissions work, as long as you have the invoices. I received almost $600 back! I had to mail copies of my invoices in to a special address you can get from your dealer, but it was well worth it.
Good luck,
