How do I tell if I have a return style or returnless fuel system?
-
In an effort to save money and also meet stricter emissions standards, Ford decided to make all of it's vehicles with returnless fuel systems starting in May of 1999. These new fuel systems allow for greater control of fuel, thus allowing Ford to get better gas milage and lower emissions. So, any car producted before 5/3/1999 has a return style fuel system while those produced on and after 5/3/1999 have a returnless fuel system. To determine your car's production date, look for a sticker on either your passenger's or driver's side door jam that has the vehicle production date.

How do I reprogram my keyless entry?
-
Cycle the ignition from OFF to RUN 4 times within six seconds, then turn it back to OFF. The alarm light will stay on to confirm programming mode. Press any button on the first transmitter. Alarm light will flash to confirm transmitter programmed. Press any button on second transmitter. (Up to four transmitter total possible) Turn ignition to ON. Alarm light will turn off to confirm end of programming mode. If you car didn't come with remote keyless entry, then I don't know if this will work. If it did, but you just didn't get a transmitter, then it should work.

What is this "self diagnostics mode" I keep hearing about?
-
If you use a certain procedure (described further down), you can gain access to Diagnostic Trouble Codes (DTCs) and many other digital readouts from the trip computer display built into the Cougar's gauge cluster. Items that are displayed include, but are not limited to: RPM, MPH, Battery Voltage, Engine Coolant Temp, DTCs, etc.
1. Hold Down "Units" & "Reset" buttons on the trip computer while the car is off.
2. Turn the car on ... The gauges will reset (pet out) and then return to normal.
3. Release the "Reset" button, THEN the "Units" button ... in that order or it may not work.
4. Push "Select" to go through various Diagnostic Modes, press "Units" to switch between Standard and Metric measuring units, and press "Reset" to return to normal mode (gauge needles will peg out again).
