1999 Honda Civic Si 4 Cyl 1.60L

Engine

Car revs between 1-2k rpm when idle

When I start the car it's fine at first, but after driving for a minute or two, if I stop at a stoplight it revs up to 2k rpms and drops suddenly down to 1k rpm then goes up again over and over. After about 6-7 minutes of driving it no longer does this. Also, if I give it a little gas it also stops dropping.

Probably has a bad idle speed control on the throttle body. I will assume that the cooling system is full and not severely low on coolant.

I appreciate your response. I added coolant and it fixed the issue.
