Looks like the EGR system is clogged or the EGR control failed. Insufficient flow or clogged EGR usually won't cause driveability problems, however it could fail the car -depending on your state - on the emission inspection. You need to take it to a mechanic and ask them to check the system, it might just need a cleaning. Zee
