Check your fuel pressure to make sure you have good pressure. I think it needs to be about 40-60psi. IF thats ok then if you have a cable actuated throttle body I would look at the idle air control valve.

The fuel pressure spec is 60 to 66 PSI and cannot be below 55PSI.
Check to see if you have a security light on or flashing when you try to start it.
