Dont forget to decarbon the engine.. clean/polish your intake ports really good if you can as well or let the soak cyl's soak with either Engine Tune by BMP or the actual Chrysler/Dodge Foaming Decarboniser.. follow the directions in the TSB or on the can closly and have your cat checked.

Thank you all for the tips. I made sure I routed all of the plug wires correctly and that did not help. So I removed the throttle body and found a small pool of oil in the back of the intake. I will be ordering the Hughes V8 MAGNUM PLENUM REPAIR KIT soon. Hopefully this will fix my #8 misfire issues. I also read that it is a good idea to replace the O2 sensors as well if I have a bad plenum.
