Ok..... Let us know how long they last before they stop working properly or you start having new problems. Motorcraft or Autolite are the only spark plugs that should ever go in a ford truck motor. All others
A) Don't work at all
B) Stop working right after a while
C) Reject them completely, literally, shooting them out of the block.

I think you probably isolated the previous issue to your old plugs needing to be replaced. Just know you may be doing it again soon with those NGK's.

When was the last time you cleaned your injectors? I have Ford clean mine every 50,000 miles and notice an improvement in power delivery and smoothness.
