I have an 02 Lincoln LSE V8, and heres what happened. I had about 20 miles left so I went to the gas station. I filled up the car to almost half way. After starting the car, the fuel arrow went up, but the computer still showed 20 miles. I continued to drive until it went down to 0 miles, but the arrow still shows that I have gas!!! How do I fix the incorrect computer display?
