94 wagon fuel smell and poor MPG
Recently bought low mileage 94 wagon with sub 90K. Very clean. First few tanks were 25-27 mpg overall average. Suddenly I'm hard up to break 20 mpg and I can almost watch the fuel guage move. After warm up fuel smell adorns the cabin. Had O2 sensors replaced. Problem persists. Runs fine. No codes. Less smell with vent/ac fan off and drivers side windows shut. No puddles, no damp spots underneath. I'm wondering if there is a well known malfunction that causes these conditions. So far after searching forum the guys with the same type issues come up with "you're on your own" let us know what you find out. We bought the car hoping to save some money on gas and repairs.
Don't have the dough to pay full shop rate to trouble shoot a vague issue. Mechanic couldn't smell the fuel, even though my 9 year old could. (and so can I) HELP!
