the problem is it stalls and when i start it, it gives itself gas and then none then some gas and then none on the very verge of stalling if i try to give it gas it stalls, sometimes if i pump the gas pedal i can get the rpms up or it stalls i've checked the all the vacuum lines and cant find anything im getting a new oxygen sensor cause it hasnt been replaced ever please help me i wanna drive sooo bad and i cant drive any other car if you have any quiestions please ask

well reaplcing the oxygen sensor did fix the problem thanks for all the help ;)
