Drop in RPM on Freeway... Ideas?



Yea, but I've been running +4's from the time I got the car.  I was just
changing new for old, the problem hasn't happened since.

If the car had been running fine and then you made a change to the car,
then 
the car does not run the same as before, that would lead me to believe
that 
the problem is due to the change you made. Im betting the car is not
liking 
those +4's you put in. Im not surprised, I've never heard anyone on the
list 
saying they have had success with this plug. I'd switch plugs.
