My gas gauge doesn't work just goes full when you start car and then goes empty after I stop have been idling at a light. And then sometimes it'll come back to full when I turn the corner.

What is your question?

When starting the car gas gauge goes full until I STOP at a light it's goes to empty and then sometimes after you turn corner it will go back to full. So I been going by my trip gauge to know when to fill up my car been operating this way for over a year. Also the gas tank and fuel pump have been replace 5 years ago due to a recalled yrs ago
