OK, if you replaced the EGR hose, did you go all the way to change the EGR Valve? A stuck open EGR Valve can cause a rough idle and almost make it cut off.
Also, a vacuum leak on the EGR valve can cause a rough idle.

Exhaust Gas Recirculation (EGR) Valve Removal & Installation 2.0L Zetec Engine NOTE: When the EGR tube is disconnected from the EGR valve, it must be discarded and a new EGR tube must be installed. The aluminum threads on the EGR valve must be inspected, and a new EGR valve installed if the threads are damaged.
To Remove:

1. Disconnect the negative battery cable.
2. Remove and discard the exhaust manifold-to-EGR tube. Use the following as a guide:
3. Raise and safely support the vehicle
4. Remove the splash shield
5. Disconnect the EGR tube fitting
6. Lower the vehicle
7. Remove the air cleaner outlet pipe
8. Disconnect the EGR tube from the EGR valve.
9. Detach the vacuum line and remove the two retainer bolts.

NOTE: The EGR valve sealing surfaces are soft metals and easily damaged.
To Install:

1. Installation is a reverse of the removal process. Carefully clean all sealing surfaces and install a new EGR valve gasket.
2. Install a new EGR valve tube.

Detach the vacuum line (#1) and unbolt the EGR valve - 2.0L

3.0L (4v) Engine To Remove:

1. Disconnect the vacuum line.
2. Disconnect the EGR tube.
3. Remove the EGR valve and discard the gasket.

NOTE: The EGR valve sealing surfaces are soft metals and easily damaged.
To Install:

1. Installation is a reverse of the removal process. Carefully clean all sealing surfaces and install a new EGR valve gasket.

Detach the vacuum line (#1), unthread the EGR tube (#2) and remove the EGR valve bolts (#3) - 3.0L (4V)

EGR Valve Testing

1. Install a tachometer on the engine, following the manufacturer's instructions.
2. Detach the engine wiring harness connector from the Idle Air Control (IAC) solenoid.
3. Disconnect and plug the vacuum supply hose from the EGR valve.
4. Start the engine, then apply the parking brake, block the rear wheels and position the transmission in Neutral.
5. Observe and note the idle speed.
   

If the engine will not idle with the IAC solenoid disconnected, provide an air bypass to the engine by slightly opening the throttle plate or by creating an intake vacuum leak. Do not allow the idle speed to exceed typical idle rpm.
Using a hand-held vacuum pump, slowly apply 5-10 in. Hg (17-34 kPa) of vacuum to the EGR valve nipple.

1. If the idle speed drops more than 100 rpm with the vacuum applied and returns to normal after the vacuum is removed, the EGR valve is OK.
2. If the idle speed does not drop more than 100 rpm with the vacuum applied and return to normal after the vacuum is removed, inspect the EGR valve for a blockage; clean it if a blockage is found. Replace the EGR valve if no blockage is found, or if cleaning the valve does not remedy the malfunction.

EGR VALVE IS #2.

Please wait for second post to answer your second question....comes with a few pictures.

yes the passages can be cleaned. They pass exhaust gas into the intake maniflod for reburning.

It could be the DPFE that controls the EGR too. Diff. Pressure Feedback EGR.

there is also a vacuum regulator valve and a solenoid too.

Please rate as fixya if this helps.
