Dielectric Grease use
kitchenguy should fill his info in, -so that it displays top right corner as everyone else. That might help in the future.
Thanks GLC for your post re-allignment.
Anyway, didn't want to re-invent the wheel all by myself, so I used a small amount of dielectric grease around the inner perimeter of the boot up to the spring, lite coat on plug ceramic and a small amount around the outside top of boot. The engine appears to running very smoothly but until the obd is read again I will not know for certain if (304) has been eliminated. This said, if the code persists what would be the next logical course of action to pin point the missfire cause?
Thanks again

If the plugs and wires are new, you can swap the 2 coil packs and see if the miss changes cylinders. You can do the same thing with the injector.
Did you disconnect the battery for 15 minutes to clear all the codes? If so and the CEL hasn't come on, you are good, so far.
Did you use a small amount of grease in the boots at the coil end too?

I was planning to grease the wire coil ends but the new Motorcraft wires were already pre-greased at the coil ends so I didn't. Was wondering why they would take the time to lub the coil end of the wires and not the plug ends as well? Are you sure if the battery is disconnected for a while the OBD computers memory of that 304 code will be eliminated or should I have a reader put on it and erase the fault, and then cycle the system with some mileage?
Powering down or erasing the code results in the same action.
The PCM has to retest all the PIDS from scratch.
There will be a code P1000 until all the tests have passed.
The only difference between a power down and an erase is the power down reboots all the tables that had "learned" the driving conditions.
An erase does not cause this action, only a retest of all the PIDS.
What you might see after a power down is the motor acts a bit different until all the tables have been altered by normal driving again.
For example, if you were to tow a load/trailer some distance, then unhook, the motor might feel a bit more powerful until the tables revert back to conditions of normal unloaded driving.
The PCM actually adjusts the fuel and timing tables in response to heavey amounts of throttle that causes the TPS to work out of it's normal range, changing the ignition timing etc.
The system is smart and can change it's program up to about 20% to meet conditions over a certain range of driving conditions.
It's when any table, diagnostic or operating, falls outside limits, that codes are set to tell you something is wrong.
Good luck.
