Starts and stalls, abs, odometer & speedometer out


Check for coolant temp sensor fault, It will affect cold start and idle. It controls open loop mode in the ECU (cold, high idle, open loop) Perform an OBDII scan of the stored fault history. Also make sure coolant level is correct.

High/rough idle on Ford Expedition


i will check idle speed sensor, most likely this is the problem, and the fuel consumption problem can be related to O2 sensor which makes the car idle very badly, so i suggest you check both
thank you
good luck

2007 crown vic 4.6 l idles high on startup


This sounds like a normal condition.What happens is the cold start emission reduction component monitor(software program in the computer) is running.
Cold Start Emission Reduction Component Monitor
The Cold Start Emission Reduction Component Monitor was introduced for the 2006 MY on vehicles that meet the
LEV-II emission standards. The monitor works by validating the operation of the components of the system
required to achieve the cold start emission reduction strategy, namely retarded spark timing and elevated idle
airflow.
When the CSER strategy is enabled, the idle air control system will request a higher idle rpm, elevating engine
airflow. While this CSER elevated airflow is requested, the low airflow test compares the measured idle airflow from
the MAF sensor to the commanded idle airflow from the idle air control strategy.
