My gas mileage has gone down. Any suggestions to help get it back up?
Are they the double platinum plugs? I hear the singles are not good for our year without the distributer. Also at 100,000 miles the 02's should be replaced. I just did mine on my 01 with 155000 and noticed a huge difference in mileage.
