If I slow down quickly when the tank is reading less than half the car will occasionally stall when I come to a stop, more often when there is less gas in the tank (no problems just driving along). Sometimes I can catch it and keep the revs up. Also I can't get more than 7.5 gallons in the tank (holds 11 gals) when empty and the gauge reads below full (~8/10ths) when I fill it up. I've looked under the car and can see no dents in the gas tank.
