This should be fuel injected. But it is throttle body and it is an early one. It has a choke coil mounted to the passenger side of the throttle body. It doesn't run a choke it just controls fast idle. It might be bad or unhooked. Check for power on this.

    Also, try to get a code tester (or stop by an Auto Zone or similar store) and have them check for a faulty Throttle Position Sensor (TPS). It is mounted on the passenger side of the throttle body and connected to the throttle plate shaft. One of my 1985's has eaten three or four of these in its lifetime.

1994 crown victoria engine races


Problem with idle speed. The idle is controlled by the pcm (engine computer) through the operation of the Idle Air Control valve or motor. But several other sensors are also at work, like the throttle position sensor, the coolant temperature sensor, the MAP sensor or the Mass Air Flow sensor. The computer monitors all engine conditions to optimize performance and driveability-this includes keeping idle speed correct.
Would probably help you if you could see what all those sensors are telling the pcm-so you need a scanner capable of giving live stream data. And don't forget, your '94 is OBD-1, not OBD-II like all cars since 1996 on have. A garage should have such capable scanners, but they are kind of high end, not your typical cheap code scanner.

Change the filter and fluid. This car if the transmission is original should have a torque converter drain. Drain the torque converter also,it gets almost all the fluid out of the transmission. Doing this the car will require almost 12 quarts of fluid. Worth a shot. I change mine at 25000 mile intervals.

I dont see if the turn signal light has to do any thing with the engine shutting off, make sure the IAC idle air control valve is working, air filter is good, fuel filter is good and IF your vehicle has a power steering pressure switch then that could be causing it but with 1985 Crown Vic I dout it.

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.
