check for vaccum leaks and make sure all cylinders have proper compression

If there is an egr valve on the car make sure it's working correctly and not sticking open. There should be no vacuum going to it at idle. The f/p should be set around 39psi.

30psi is too low while running at idle. How does the car run otherwise under cruise and load conditions?

OK, so has it always been like this?
Have you changed something and then it started?
What's your mod list?
