The throttle body and idle air control motor needs a good cleaning. Use brake clean and a toothbrush and clean inside the throttle as best you can. especially the back of the throttle plate and where it sits against the throttle body. Start the car, it will take a second or so. Then rev it up and spray some cleaner in the throttle keeping it running. This usually takes care of the up and down RPM's. Have the codes checked to see what is going on. It could be the idle air control motor. Let me know.

SOURCE: Check Engine light on Acura TL 3.2 1999

You can turn off the Check Engine light by either disconnecting the battery or by using a code reader to clear the codes. However, if the problem still exists it will come right back on. Instead you should get the code read, find out what the problem is, and fix it. Your local autozone or checker auto parts store will read them for free.

SOURCE: engine revs up and down

Sounds like a bad IAC motor, or a vaccuum leak, or low coolant... I would definately start with checking these things first
