Random Reving

I have 92 Acura legend L. I have a problem with the motor just Reving up and down up and down, it only happens when I have been for a short drive just 10 mintues at 50 mph when I put it in park it either idles at 1000 rpms or revs constantly. I think it might be a vacuum leak but I am not sure. Any help would be appreciated. Thanks.

Spray the vacuum hoses with carb cleaner, if the idle speeds up it's a leak. The throttle body may need cleaning. (best to do this with the engine cold).
Thanks I will try that first thing in the morning.
Your welcome, Also if your coolant level is low or air is in the system it will cause the idle to fluctuate.
or could be your pcv valve , it could cause the self revving problem , as it happned to me not to long ago ,
