Question about 2002 Ford Escort
Starts and immediately go to 2500 RPM. After 5 or 6 seconds, it will idle down to 1200. It won't go lower.
Clean out the throttle body carefully and replace the auxilliary air idle valve. There is a resetting process for this valve so dont just fit and hope!
Check on Google or forums but i think ...when fitted you turn on ignition but dont start car , then put the accelerator pedal slowly to fully open, hold it for a min then release. start and drive car until warm and the recheck.
If the idle is high then settles it is not an air leak. It is something stuck that then releases which is only throttle flap or idle valve. It is always a goid idea to replace fuel, oil, air filters on normal service intervals.

SOURCE: i have 1990 ford f150 5.8 liter it idles high when in park and idles about 1200 rpm when in gear and sometimes surges up and down. i have clean the idle control and check showing 12.5 ohms still won
One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

This is usually caused by having a vacuum hose come off or
connected to the wrong place. The diagram is under the hood.
Also the cold air bypass could be dirty and need cleaning. I use
carb cleaner in a spray can.
Other check air filter, plugs, wires.
