Could be sticky turbo vanes or a sticky EGR valve. EGR valve is the easiest to check. You can also see if your EGR cooler is leaking at the same time.
Park your vehicle nose down overnight. First thing in the AM, pull the EGR valve and look for signs of wetness in the intake manifold - if so you have EGR cooler issues. Normally it should be very fine soot and perhaps a little oil from the crankcase vent. Even if it is dry it may feel oily. Take a little bit and set it out in the sun to see if it dries out or not. Other wise clean up the EGR valve, just be careful not to get anything inside the valve body itself. May want to pick up some new O-rings and gasket for the valve cause you may trash them when you remove the valve. Also, try to vacuum as much crud out of the intake manifold.
Valve can be hard to remove. I remove the bolts and connector, rotate the valve slightly, and if I cannot simply pull it out, I take some rebar tie wire and loop it thru the bolt holes of the valve, and then around a 5 foot 2x4. The end the 2x4 rests on the cowl/firewall, and you can push up to pop out the valve. Just make your wire and board arrangement such that you are pulling straight up on the valve.
