I just bought a 93 RX7, when I got it I got about 350 miles to a tank, and now (three weeks later) I am down to about 200 a tank. I have noticed that as the mileage to gallon was dropping the smell of gas had become more and more evident, however upon inspection there seems to be no fuel leak. Also tends to be a rough idle around 750. Was wondering if any of you guys/gals have had this problem as well, and what did you do... Thanks in advance. Also the car came from california so not sure if it may be the fuel/air ratio. as I live in Washington. Thanks y'all.

350 miles to a tank? Thats really really good. I only get about 260-280 drvinig really nice.

Try changing the fuel filter. Also if you haven't changed your fuel pulsation dampner...now would be a good time
