1997 986 w/ 46k miles manual 
Well as I was entering the freeway today after some spirited driving in the hills, I had to pass a vehicle to enter the freeway.  As I was speeding up (no redline, but close)) my check engine light  came on!  I pulled over right away to check to see any signs of obvious damage.  Did not notice anything. 
Checked oil -OK 
Started the car again and starts up right away.
No sign of power lose.
No strange noises.
Question is it okay to drive to work tomorrow 5 miles away and fix it when I get home?
Can I turn off the CHECK ENGINE light and drive to see if it comes back again?
I've read that I might need new spark plugs or a coil pack.
It was a very scary and stomach turning 

 feeling after reading all about what COULD happen when the engine light comes on.
Thanks in advance for all your help
