The car had a dieing issue,supposedly the crank sensor.That's been replaced.The ignition module changed(so the manifold has been off-this latest issue since the manifold was off.I don't know if it's related,or something connected to the first problem.
Possible causes for the idle to be in the 1100 to 1900rpm range? Thank you. on 2002 Ford Taurus
Check all vacuum hoses .test the idle air control motor.Any codes? Brake booster check valve/hose hooked up?
