car runs out of gas at 1/2 tank

Have the fuel sending unit checked-start here

Have you had a fuel pump or work done recently that involves fuel tank or sender removal ? If so remove the sender and check to see if it has full travel and if the fuel pick up is in the correct location bottom of the tank. Let me know how this works out.

That was rough idle. I meant. and I just bought the car so i am not sure.But I am planning to have the tank dropped to check it out thanks

No problem let me know how it works out .

My '97 Tracer started doing the same thing around 125k. Same problem: appeared to be using more gas but took only a few gallons to fill up. By chance, I was at Auto Zone for something else when the sales guy asked if I ever had my car hooked up for a computer read out. He kindly did this for free and I discovered the problem is with my tank meter. Happy to know this old car still gets good gas mileage at 145k. Reading around, the rough idle, near dying, or dying is most likely a worn vacuum line. Both problems are just basic wear and tear everyone experiences. It's a great car.
