95 bronco power surging

when I accelerate while driving the engines power feels like it is surging. Like it feels powerful,then weak, then powerful again. This worsens with the a/c on. Driving me crazy :runaround:!!!!

Auto Zone or Advanced will check for computer codes free. I would get this done.
I would check fuel filter,ohm plug wires look closely at distributer cap. Pull the vacuum hose on the fuel pressure regulator if fuel is in it replace.

I have a 94 Bronco doing the same thing. But I also have added a set of headers to my car since I had a cracked exhaust manifold. Now the egr pipe is cut and a check engine light on and a ccode reads egr bad. Not sure how to bypass this system. Any further ideas.
