I have check to cleaned the throttle body, idle air control valve, and made sure the plastic screw was nice and tight. I have replaced the battery but it will still have trouble starting up once in a while. It'll start then die. The idling problem happens after the car is warmed up and in park or in neutral. After I put the car into drive and give it some gas it will jump forward and move at a faster pace than normal.
I have also checked to make sure there was no air in my coolant but no luck. please help thank you

 

sounds like you just have a vacuum leak, you need to find the vacuum leak
