1998 Saturn SL2 cruise control

Engine Performance problem
1998 Saturn SL2 4 cyl Front Wheel Drive Automatic

recently my car stalled for the first time while I was inline at a drive through. It took three cranks but eventually it started thank god, now the vehicle seems to be driving like it is cruise control. I take my foot of the gas and and continues to accelarate and takes a long time to deaccelerate. Also when I apply the break it revs up to 2 on the rpm meter, just seems like the engine is getting gas when im not applying it, also I might me paranoid but it looks like there is gas leaking from under my car I noticed in the parking lot this mornig, any suggestions, like maybe fuel pump or 02 sensor or something
