Bad fuel mileages...

I have a 90 240SX with a stock KA 2.4l sohc motor. On a full tank I can drive about 150-170 miles (both city and highway). I've already changed all four fuel injectors, o2 sensor and fuel filter. What else could be the problem? I don't think its my air flow meter because the car is still got power for what's it worth.

Please let me know what else i can do...

Thanks in advance!
