1997 Ford Taurus Question: Need to know the problem?
Answer #1Bret Bodas from RepairPal Test Shop, February 17, 2009, 11:07Master
If the idle speed is too low, or the system, that controls the idle speed is having a problem, this will happen. I have seen many complaints about the idle valve on Fords, sometimes they can be cleaned and this may fix your issue.
