Rpms bounce up and down while accelerating - 1997 Honda Civic

When bouncing, does the engine speed go up and down. If not, the gauge may be bad, or if the engine sounds like it speeds up, try cleaning the throttle body by spraying throttle body cleaner into the intake/throttle and wipe clean with a clean cloth. Do this 2x's. You will have to remove the intake pipe that connects to the filter box and intake. After cleaning this, it may seem hard to start for a second, it's because of the cleaner. Don't worry it will start.
