There could be lots of things involved. Observing scanner readings would go a long way in guiding you.

2908752759 things could be the cause.

Mods?
Tuned?
Need a lot more information.

As Shbox mentioned, a data logging scanner that reads real time data would be a great tool to use.

Can a guess an aftermarket TB with the IAC bypass not done????

I suspect if you had a scan tool you would see the IAC maxxed out.

Could be mechanical issues or a bad tune too.
