How long has it been since you changed the plugs/wires? What year is the car? Checked the dpfe? Look around for vacuum leaks.

I'd start with checking for vacuum leaks, the plugs and wires, and work my way from there. Shouldn't have a problem with the dpfe, but it's a possiblilty.

check to see if the wires aren't in contact with the EGR tube.

My car did that just about 2 months ago. I replased my DPFE and haven't had a problem since.
