I'm almost pretty sure its not a fuel issue although about a month ago ive been noticing a heavy fuel smell in the car after drivin about 10 or more min. mpg hasnt seem to drop and with my windows up I dont smell it which makes me think its a rear hatch seal lettin in the fumes, anyways I was wondering if I should invest in maybe aftermarket igntion system maybe just a new coil and new cap-n-rotor , I'm open for suggestions.
