i bought the car and it had been sitting for 4 months. fixed all the other problems and put tons of gas treatment in it. after running it for a few days it stopped bogging and sputtering. then i had to let the car sit until i fixed a suspension problem for about 2 weeks. now the car idles fine but when i press the gas it almost completely stalls out unless i let off the gas. i just replaced the fuel filter as well. any helpe would be great. im carless for now.
