Actually check the egr valve. It basically creates a vacuum leak. If it's bad it will have hard start and impossible to idle. Or iac valve
There are couple of things I would check out that would cause this problem. \015\012

\015\0121. The Mass Air Flow Sensor. It measures how much air is going into the engine. Should be located on top of air filter box.\015\012

\015\0122. The air tube that goes from the Mass Air Flow Sensor to the throttle body. Check for leaks that would bypass air from going through the Mass Air Flow Sensor.\015\012

\015\0123. The Throttle Position Sensor. Located on the throttle body. This tells the computer what position the butterfly plate is on the throttle body. You control this plate with the gas pedal..
