my friend is a mechanic but he thinks my car has a bad gas tank filler neck. but heres whats going on. at first kept thinking its the gas cap since its the evap p0440 code but we have replaced it once already. last mpg reading was 25 but max is 30 but once i got 36( i keep thinking now i should be getting this mpg). also one time it was reset by unplugging battery and its was off for almost a week(that tells me its not gas cap) then turned back on while driving. my brother thinks though that im running rich or using more gas than it should. im going to look at the filler neck and see if its rusted or bad and go on from there. but help me out if you guys can. also 8/13/13 was last fill up and as of right now its half way empty.
