Ok, checked the codes with the Engine running this time, and pulled the following:
21
34
74
77

Too many if you ask me.

(pulled the electrical connector off the IAC and the engine sputtered and died, so I don't think that's bad.)

dude go here http://fordfuelinjection.com/?p=14 theres all the codes you need, and they have columns for when you found em aka KOEO etc...

it helps a lot more if you can report the condition, not just the code. i doubt everyones got em memorized. just to dang many of em.

i dont know if this is of any use but i know i tested this once wih my car (unplug the IAC) and when it was cold it died right off the bat. but when warmed up it actually ran. the idle was LOW but it did run. maybe my throttle stop screw is holding the throttle open a little? just food for thought...

Ok well, lets see here:

21-   ECT out of self test range 0.3 to 3.7 volts. -Don't have a clue
34-    PFE or EVP circuit above the closed limit of 0.67 volts. -Again, don't know what this means.
74-    Brake On/Off switch not actuated during KOER test (user error).
77- System failed to recognize brief WOT during Dynamic Response Test (user error).

It's funny, because some sites say that code "34" means No EGR flow and others say different stuff. What am I to believe? Should I take off the EGR just for the heck of it?

I think the TC throws a 34 even though there is no issue because of some recall that was done. You may or may not have egr issues but it does explain a possible 34 code

21 will come up if you run codes on a cold engine. If engine was at operating temp you may need a ect sensor, or have a problem in that circuit.

as already mentioned fordfuelinjection.com is a great resource.

I remember doing the code pull thing in 1985 no internet or anything just some service literature I pulled at the library......those were the days LOL

start throwing snow balls now cause all you guys are freaking idiots for using and promoting that site - fordfuelinjection.com

The guy can't solder nor does he point out the correct preparation to solder correctly,,, he fails to mention critical steps that probably caused you to get codes 74 and 77,(cut the wheel, step on the brake ect prior to even pulling codes), the list goes on and on and this guy has said you can clear the codes on your computer by just unhooking the battery for 15min!!!!!!!!!!!!!!!!!. The only way to clear any codes is to unhook the sig rtn to sti connection during the time in which that specific code is being dumped out to you.

he also says you can use your digi meter to pull codes if you leave it set on continuity to listen for the beeps,, now thats curious,, ill have to jump right on that and set my meter to resistance and let current pass thru my "ohmmeter".

i looked at those code pulling instructions for some time trying to figure out what the heck to do and i got lost. seems to me that i would have my sti and sto hooked up to the neg bat terminal as far as i could tell.

I use the voltmeter method and use a 12vdc buzzer instead of the actual meter.

this guy does not even make mention of what to do with the Signal Return connection.

stupid,,,,,,,,,,,,,stupid,,,,,,,,,,,,,,,,stupid.

you need to start over and follow the instructions here,,,,,,,,,
http://www.therangerstation.com/tech_library/OBD_I.html

the fuelinjection.com site might have some goodies but just the fact that each tab i looked at had some problem, it bugs me. Take for instance the "Tech" secion on relays. A man would think there would be some "above and "beyond" information on relays,,,well,,, there was nothing inpressive.

i dont know why youd have to do a search
the 74 and 77 codes are your fault ,, you did not do the test properly.

Clearing Codes
These codes are kept in memory for 40 warm up cycles. To clear the codes for purposes of testing or confirming repair, perform the code reading procedure. When the fault codes begin to be displayed, de-activate the test by either disconnecting the jumper wire or releasing the test button on the hand scanner. Stopping the test during code transmission will erase the continuous memory. Do not disconnect the negative battery cable to clear the codes; the keep alive memory will be cleared and a new code (19) will be stored for loss of PCM power.

Malfunction Indicator Lamp (MIL) Method ***using your [COLOR="Red"]check engine [/COLOR]light as the test light.

The Malfunction Indicator Lamp (MIL) on the dash (Engine Light) can be used to retrieve the stored codes. This method does not allow for any system investigation. This should only be used in the field where quick checks are needed. Follow the directions previously given for the scan tool procedure. To activate the tests, use a jumper wire to connect the signal return pin on the diagnostic connector to the Self-Test Input (STO) connector. The self test input line is the separate wire and connector with or near the diagnostic connector. Codes are transmitted with a pause between flashes. Code 32 would be sent as 3-flashes, a pause and then 2-flashes. A slightly longer pause separates the codes. The only way to repeat the code is to recycle the system. The Continuous Memory Codes are separated from the other codes by 6-seconds, a flash and then another 6-second delay. Compare the 2-digit and 3-digit Diagnostic Codes with the appropriate chart[COLOR="red"].********FOR THIS METHOD, YOU DONT NEED A METER OR A TEST LIGHT, JUST A PAPERCLIP*******[/COLOR]

[COLOR="Red"]((SEE DIAGRAM AT THE BOTTOM OF THIS POST FOR HOW TO INSTALL YOUR PAPERCLIP ONLY)))[/COLOR]

---------------------------------------------------------------------------------------
KEY ON ENGINE RUNNING (KOER) TEST

1. Make sure engine is fully warmed. If in doubt, run engine at 2000 rpm for 2 minutes.

2. Turn ignition off and wait 10 seconds for system to shut off. Make sure A/C is off and transmission is in Park (automatic) or Neutral (manual).

3. Hook up light and jumper (or tester if you have one).

4. Make sure vehicle is safe to run and start engine.

5. Engine I.D. should be output.

6. Step on brake and turn steering wheel 1/4 turn. If the vehicle has an overdrive cancel switch, push it.

7. If a "Goose" pulse is received, move throttle quickly 1/2 way down and release.

8. Fast Codes are output (ignore).

9. Read codes.

10. See code explanations and check components as necessary. Use FIRST CODE OUTPUT and retest after any repairs are made.

Ok well, lets see here:

21-   ECT out of self test range 0.3 to 3.7 volts. -Don't have a clue
34-    PFE or EVP circuit above the closed limit of 0.67 volts. -Again, don't know what this means.
74-    Brake On/Off switch not actuated during KOER test (user error).
77- System failed to recognize brief WOT during Dynamic Response Test (user error).

It's funny, because some sites say that code "34" means No EGR flow and others say different stuff. What am I to believe? Should I take off the EGR just for the heck of it?

You have to realize that the only reference material that will that will define the codes specifically for your car are the Ford shop manuals for the year of your car.

These other reference materials are a composit of all years and engines over the life span of the EEC-IV.
Or if in a forum maybe just for the engines and years of vehicles involved in the forum.
There is a lot of commonality between them but also a lot of differances.

The EGR codes refer to PFE and EVP.
You have to know what kind of an EGR system your car has.

PFE uses a pressure feedback sensor.
EVP uses a EGR valve position sensor.

It takes some experience to gleen what applies to your car from the reference material.

Oh for Christs sake. KISS

Keep It Simple Stupid.

Here we go.

Code 34- does the EGR valve have a green and black check valve inline? If so, your EGR recall has been done, and the code 34 is not a concern.It is NORMAL.

Codes 74 & 77- Operator error. NOT A CONCERN.

Code 21-Common if you didnt let the car warm up. If it was warmed up, ask Pete D over on http://www.turbotbird.com to send you the ECT testing proceedure. A faulty ECT will not always set a code.

ALSO LOOK AT THESE:

http://www.turbotbird.com/techinfo/eec.htm

http://www.turbotbird.com/techinfo/In_Car_Codes/In-CarCodes.htm

THESE ARE ALL OF THE RESOURCES YOU NEED.

People tend to complicate things WAY too much.

And just for the record, My vote is for your TPS to be way out of range, or a combination of that and the ECT

Hey Birdman, yes...you. I don't know if you got my Private Message or not, as I sent it out quite some time ago, but I was wondering if you still have those pictures you took of your Black Turbo about a year ago?

(I agree with keeping things simple by the way. I love KISS'ing things)

ill play Pete for now,, since the ect test procedure is in my DIY link:D

ECT sensor test
Resistance test pin to pin of the sensor (this is a variable resister proportional to temperature

including outside air temp if the motor is cold)
at 50degF=58K ohms
at 65degF=40K ohms
at 180degF=3.6K ohms
at 220degF=1.8K ohms

Sorry guys I missed the question about pics of my mityvac hand pump. here is a link to the compnay site. http://www.mityvac.com/ The first page has a pic of the one I have.
