I was driving.

All of a sudden, as I remember, my engine starts "freewheeling" - meaning
there is no resistance - and my engine is running at a very high speed
"redlining"

I stopped the car, and started it again, in nuetral as I remember, and the
car is redlining.  I am at home now, and the car is 10 miles away, so I
can't just run out and make observations.  But one thing is for sure - I
start her up - and the car redlines

Any ideas??????

I at least want an idea of what could be wrong before I tow it to a
mechanic.

Thanks in advance.
