I just got a 2002 windstar limited last weekend and sunday got an error code for the emissions, got the code read and replaced the egr valve pressure sensor, after doing that the van started bucking under excelleration, then tonight when I got off work it did it while in park??? What gives and can anybody help me?

That could be something as simple as fouled spark plugs, bad wires, etc... Another potential cause may be a bad transmission sensor as that was a problem I had with a contour last summer. I'd start with all the simple and usual culprits for these problems before investing too much time and money into something that isn't broken. The error codes generated by the computer only can tell what sensor(s) is giving readings outside of normal operating parameters, not the root of the problem, so good old fashioned trouble shooting is still important.

check the sensor and the vacuum line to the EGR
also check the PCV valve

was it a p0401 ? If it was you should have never touched the EGR system.
