Eats gas
 

I have a 2007 ridgeline rtl. Boy does it eat gas. Changed filter, plugs, etc..., but still gets poor mileage. Any ideas as to why? They say it should get 15 miles in city. I'm lucky to get that on hwy. Thanks

I read somewhere that gas mileage will drop radically when the valves are out of spec and need adjusting. Are you getting any codes?
