After running my Miller 212 welder for a while the 250 starts running rough and losing rpm. If I shut welder off and 250 idles for awhile it runs great for a couple minutes then same thing.

what you realy need to do is check your fuel pressure. it sound like a fuel pressure regulator . but ive also seen a dirty fuel system and defective fuel pumps do the same thing.

There will be an egr control solenoid that allows vacuum to reach the egr solenoid, sometimes it will be called the egr vent solenoid. It is probably bad.

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).
The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.
My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.

your egr valve might be faulty bring it in to the auto parts to have it check out what your looking for is the 32 code on the OBD II scanner.
