I installed my new platinum +4's last Saturday and the first thing I noticed was a rough idle. I though no biggie, so I took the foci out for a ride but thanks to my fuel pump and 1/4 tank of gas I could not really get on it. So I have been driving now on my second tank of 92 oct fuel and I am having nothing but trouble from these things. I still have a rough Idle, my midrange is going flat fast, and my top end is nonexistent. Anyone else have these problems? I am going back to the motorcraft platinum's...

Remove them. I have first hand experiance with them. My bosch plat regulars were wrong, and i replaced em with +4's... Still had the same problems you had... ended up having Ford point out these plugs are garbage to the tune of $50/h.
