EGR may be clogged, easy to check so you may want to start there.


just remove the 2 bolts on the EGR (rust colored thing bolted to the side of the upper intake plenum) and make sure the hole isn't clogged

What Superhereaux said. If you find carbon buildup get some carb cleaner and spray it out. The plenum could have build-up also.
