Hi, I have one problem since last year. The milage of my 2001 Accord LX dropped dramatically now only little bit above 25 mpg. I have driven it for 3 and half years and total 36000 miles. When I did my 30000 maintenance in a garage, they changed my spark plugs. And checked my owner's manual today, it said to change it after 100k. Is it a problem?
And have a weird problem also, whenever I make left turn the left side back wheel seems make noise like scratching. What is the problem?
Thanks
