Question about 2000 Ford Escort
Sounds like a faulty idle air controll valve , it is mounted on the intake and is easy to to replace however ,,, to prove out this concern use a scan tool and monitor the iac duty from the pcm .. such as the the a/c is turned on the pcm sends a ( duty cycle %) to the iac to idle up the engine to compensate for the compressor load .
an iac valve cost $60-$80
hope this helps
