I have a 2002 Santa Fe gls 4wd with 130k give or take. I have done some research and Im supposed to get 19-26 mpg... But im getting 9.... I replaced plugs and wires... Changed filters and got about an extra 3 mpg out of it... So I'm still missing quite a bit. Also when I get on it to try to merge with traffic or climb a long hill I get this burnt rubber smell(and no I'm not burning my tires). I just got this vehicle about 4 months ago. It's my daily driver and its killing me at the pump. Anyone else ever have any of these problems? And if so... How were they resolved?
