Engine Performance problem
2002 Ford Windstar 6 cyl Front Wheel Drive Automatic 166 K miles

My emissions check engine light has been on since I purchased this 2002 Ford Windstar 6 months ago. It runs fine except when I give the car gas going uphill then it doesn't want to go. Today on the interstate going up a hill it wouldn't go over 40mph and the emissions light started flashing. then it seemed to have trouble whenever I gave it gas to accellerate. Now it is running rough from the start and running rough. AutoZone hooked the computer up and it said EGR and Fuel injector Trouble codes PO 171 & 174 & 302 & 401 can you tell me if this sounds right and what should I do
