I will do that and go from there and see where I am at. Hopefully that fixes it.
Like your dad said replace the cap and rotor. Also use an ohm meter and check your plug wires too. Place a lead on each end of the wire. Your reading should be zero.
Don't forget the manifold could be plugged with carbon. You will not be able to see it you have to do the test under the troubleshooting in the article. Follow the directions for troubleshooting it could be the EGR Valve or the solenoid. You can check with AutoZone or Advance Auto to rent the tools you need. You get your money back when you return them.
