[QUOTE="Vinnie_B, post: 16679425, member: 201678"] I suggest you start your troubleshooting in this order: [LIST] [*]Check the following (PIDs) [LIST] [*]DPFEGR (if equipped) (hot idle value within 0.15 volt of the ignition ON, engine OFF value) [*]LONGFT1/LONGFT2 (Rich/Lean conditions) [*]VPWR (value between 10.5 and 17.0 volts, and within 0.5 volt of battery voltage) [*][B]If VPWR not between 10.5 and 17.0 volts: Check charging system [/B] [LIST] [*][B]If VPWR between 10.5 and 17.0 volts, but not within 0.5 volt of battery voltage:[/B] [*]CHECK the B+ voltage to the powertrain control module (PCM) power relay. CHECK the VPWR circuit between the PCM and the PCM power relay. CHECK the PWR GND circuits. [/LIST] [*]Secondary Ignition System (Wiring, Coils ect...) [*]Fuel Delivery System [*]Exhaust System [*]Positive Crankcase Ventilation (PCV) System [*]EVAP System [*]Charging System [*]Intake Air System [*]If you exhausted thru these options you might want to consider taking your car to the dealership and/or garage who has access to ford IDS to run some test on the above. Experienced tech will resolve your issue in 3 hours. Good luck! [/LIST] [/LIST] [/QUOTE]
