Question about 1985 Ford Crown Victoria
You can't adjust it, it is controlled automatically by a computer, if the idle is high there is a problem with the system.

SOURCE: my 4.6 idles erratically.
try the following, if that doesn't correct it u may need to replace the air bypass valve.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

I noticed this is 6 months old so I don't know if you have figured it out yet but heres an answer for you. On the back of the headlights there are 3 plastic heads, they turn but spray some wd40 or something on them first. You might have to take the headlights assembly out to get a good bite on them.

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
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.

SOURCE: 1988 Ford Crown Vic Strange Idle
When you turn the key on does the check engine light come on? If not it may be burned out. It sounds like a MAP sensor or an O2 sensor is bad. I would suggest taking it to autozone as they do free diagnostic and seeing if a code comes up. If it is a sensor it should, if not it may be the idle sensor not reading right in the ECU. More than likely it is one of the sensors though.
