gas on the economy is stupid expensive 1.20-1.40 EURO a liter!!! 1 EURO = 1.5X US dollar. our cars take 50-55 liters to fill up from low fuel light.
i tightned up the exhaust leak on friday and my car is at 160 miles and the low fuel light hasnt came on, yet. so that has helped out a lot but now im sure my plugs are fouled out.
o2 sensors are old they have 90k miles on them

I would suspect that your 02's are the culprit. You have changed everything else and Mustangs are known for eating sensors. I also believe that 90K miles is way beyond the life expectancy of those sensors especially since you have done some modifications to the car.
