2001 Mercury Sable LS Premium 6 Cyl 3.00L
High Idle on 01 Sable
My 01 Sable seems to idle extremely high when started (in park) and the RPM races up and down intermittently at stops signs/lights in drive with the brake on. I did notice that in park, RPMs go up considerably when I turn on the heater/defrost, and come back down again if I shut it off. I tried to clean out the air breather compartment, which seemed to help briefly, but then the old problems returned. Any ideas?
The number one cause of a high idle on this car would be the idle speed control.
