Ford Repair: idle motor for a 1998 ford escort sport, pvc valve, oxygen sensor

Question
I just had my pvc valve (it was melted) fixed, one oxygen sensor replaced, tuneup, fuel injectors cleaned, fuel filter changed (my check engine light had been coming on). It is now running great but will stall out when I am at an idle. Is their an idle motor I can buy or is it called something else?

Answer
Hello and thanks for the question...I'll try to help.
 What I would suggest to you is that you bring it back to the place that performed the tune-up. If they did a "good job" it wouldn't be stalling at idle. Also, did they check the computer fault codes and track them down for the cause?
Hope this helps,
Erik
