Question about 2000 Ford Focus
Check the O2 sensor that is attached just after the air filter. It may be dirty and could use a good cleaning or replace it.
I got this problem when I was messing with the throttle, I removed the hose that goes from the filter box to the throttle not knowing there was a sensor on that hose that tells the computer how much air is coming through the filter. So when I started the car without that hose attached, the sensor was not getting any air causing the engine to raise the RPMs until enough air was going through the sensor. Since it was not attached, the car redlined before I quickly shut it off.
If its dirty it will cause it to not read the airflow properly.
