Have you checked the PCV system?? If its stuck in the closed position then you will lack power and turbo boost. A vehicle needs 3 things to make it run proper; FUEL,FIRE and AIR. Try that and see if it helps.

Rough idle only when in gear.


The Air Idle Control Valve (IAC) may be bad or dirty with carbon build up. Check for loose wire, remove and try to spraying it with throttle body cleaner to clean the carbon out and dry it with a hair dryer before installing.
The other thing to look for to is stuck EGR valve. same process as the (IAC) as to cleaning it too. If both are beyond cleaning then replace it.
You can go to Auto Zone and have the car scanned for any DTC codes which would indicate any problems with the (IAC) and EGR's performance.
The other thing to that would make the engine shake at low RPM's is bad spark plug and wire or low engine compression, but that would give you problems through out the whole engine's performance.
Good luck and hope this helps, Start with the (IAC) and EGR as to cleaning and scanning the engine.

99 ford expedition 4.6 misses / egr? vacuum?


it's getting to much egr the egr has gone bad and needs replaced.
the diaphragm in the egr is leaking, and default position for air is defrost.so when you hit 3000 rpm you don't have enough vacuum.
