Wondering why your MIL doesn't come on? Or in other words, wondering why your truck doesn't have an O2 sensor after the catalytic converter or a bunch of other weird things, like why your state can't do an emissions inspection?

Spark plug thread and factory procedure changes.
After much hemming and hawing, I have decided to put this info in the tech folder. This is from a document that Ford provided to the NHTSA a few years back in 2005 in response to an investigation that was closed by the NHTSA because it was not deemed a "safety" issue. It was reviewed again in 2007 and again deemed to not be a safety issue because of the number of complains (total of 652 by 2007) versus the number of engines total (over 10,000,000).
My review of documents related to this (which I won't include here) show that after the model-year 2002 changes to a long-thread head, the 2003-2004 model-year shows a substantial reduction in plug blowouts. Of 652 complaints, NONE were shown to cause any damage to the hood, cause a fire, or a gas leak of any kind. Stalling was possible but again in very rare cases, and a restart was usually possible except in ONE case.
Running spark plug changes:
December 1996 - 4.6L 4V alignment feature added
February 1997 - 4.6L 2V head alignment feature added
September 2000 - WEP (Windsor Engine Plant) 2V head alignment feature modified (4.6/5.4/6.8)
November 2002 - WEP introduced long thread heads on 2V (all)
May 2003 - REP (Romeo Engine Plant) introduced long-thread heads on 4V 4.6 and 5.4
November 2003 - REP introduced long-thread heads on 2V and modified alignment feature
In 1999, and 2001, an interim fix was done for a cross-threading issue.
Original process:
Step 1 - Zero torque spark plug (air tool)
Step 2 - Torque to 16-20Nm final torque (DC Run down), monitor at 6-12Nm, and final torque must be reached within 0-360 degrees.
New process (addressed the possibility of applying installation torque for more than 25 degrees of rotation)
Step 1 - Zero torque spark plug (air tool)
Step 2 - Torque to 16-20Nm final torque (DC Run down) start monitor at 6-12Nm, and final torque must be reached within 3-25 degrees.
Another action to address cross-threading was the addition of an alignment feature to lead the plug into the hole.
