It takes a minute or more before it idle or runs better. I replaced the IAC. After the intial start my car idles and runs fine, but when I park for shorts periods of time and restart the car it sputters and seems like it has a hard time idling, if I put it into gear it doesn't want to run right away. I have to play with the throttle or let it sit for awhile before it corrects itself. I already replaced the Idle Air Control Sensor, but the condition hasn't changed.

Scan for codes and check fuel pressure first.
