Yes after you run the KOEO self-test you turn off the key. Remove the STI ground (Deactivate Self-Test).
Warm the engine. Then ground the STI wire (Activate Self-Test) and start the engine and and you are in the KOER self-test. Follow the points below and count the codes.

Engine Running Self-Test

Special Notes:
On vehicles equipped with the Brake On/Off (BOO) circuit, the brake pedal MUST be depressed and released AFTER the ID code.

On vehicles equipped with the Power Steering Pressure (PSP) switch, within 1 to 2 seconds after the ID code, the steering wheel must be turned at least one-half turn and released.

On vehicles equipped with E4OD transmission, the Transmission Control Switch (TCS) must be cycled after the ID code.

The Dynamic Response code is a single pulse (or a 10 code on the STAR Tester) that occurs 6-20 seconds after the engine running identification code. (See Code Output Format in this section.)

When/if the Dynamic Response code occurs, perform a brief wide open throttle.

How To Run Engine Running Self-Test

It sounds like to me that your Computer may be going bad.

 

ok i will do that test asap. what computer would i need certain number i need to look for. where is the ecm located on this truck

 

You need the F4????? number off the PCM Computer or the Calibration number off the drivers door post to get the right PCM Computer.
You can post the Calibration number here and we can look up the right number for you.

The PCM Computer is located in the drivers kick panel but you take it out from under the hood.

PCM Computer location:


PCM Computer plug with 10mm bolt:


The F???? number is F5TF-12A650-ALA in the photo on the PCM Computer plug below:


Calibration number "4-54E-R10" in photo below:

ok the calibration code is3-51g-r10

 

You have a 1993 truck and the computer numbers are:
The drawing number that everybody uses except a Ford dealer is F3TF 12A650-XA.
And the number a Ford dealer would use is F3TZ 12A650-XA.

 

thank u for the info. well i checked timing and it was correct. it could use a set of plugs but there not that bad. i took the connector off of the ecm it didnt look to bad little bit dirty so i cleaned it up pluged it back in buttoned her up and took it for a drive. wow it ran smooth as butter and had me thinking thats all it was. about ten miles of driving and its right back to doing the same thing. so i unpluged it again and drove with the same results. appears to run fine untill the computer relearns then it runs like crap. neeedless to say im on the hunt for a new one but am having trouble there doesnt seem to be many here around houston. one place i found has it and they want 250. is there something special about this model. thanks for everybodys help getting this figured out

 

ok well i finally got around to pulling the ecm out to look at it and come to find out it is an xb and not an xa. subford can u help me track this down to see what truck it came out of and if they are compatible. maybe the whole problem. and does anyone know of a way to test the hall effect sensor in the distributor, what voltage/ohms it should be reading. thanks for the help.
