Engine Tech / 1988 find
Mine came out of a barn last year with more problems than a math book but through Frustration, Aggravation, determination, and the help of the people on this Forum we succeeded in building a sweet car.
I have seen these cars priced over $10,000 I would not sell mine for less than $5000.

Engine Tech / 87 Thunderbird 3.8 code 13
I really do like having these forums as the people are so knowledgeable and willing to help.
Today I reset the timing as so many players were on the disable list with the OLD EEC the timing was off about 20 degrees (guessing).
I ran self test mode again and  the KOEO was still code 11 PASS.
KOER codes 44 and 94 both making me aware the air pump and it's components are disabled (I removed the pump)
I want to thank jcasidy and Softtouch and everyone else for the help on the Walking bird 87 Thunderbird 3.8.
I will soon be working on the Dirty Bird (65 Falcon 170 3 on the tree)
That's all FOLKS!!

I replaced the EEC and the ISC is now functioning I believe the throttle position sensor is also now in the game, what a difference.
The ISC does in fact retract in self test mode when things work together.

Two self tests tonight with new ISC first was similar to yesterday
The second test KOEO code 11 PASS
KOER still have codes 12 and 16

Ohm values for ISC
Old 3.1 ohms tracking switch
New 9.5 ohms tracking switch

New ISC motor 20.56 Mega ohms
Old  ISC  motor 6.4      Mega ohms

There is quite a difference

Ok Softtouch,
I just read codes again and have several, I used the test light method.
KOEO
13, 14, 31,
KOER
12, 13, 16
 As for where I have got my information for bench testing the ISC I have been reading myself cross eyed trying to troubleshoot this car. There is a lot of information out there in cyber world not sure exactly where I found any of it.
I am still confused how doing the self test with a test light 
Made the selonoids function? I have ran many self tests and this has not happened and to have vacum back at the heating rod in the intake is bizarre.
I have a bright and shinny new ISC and a new EEC, ECM, PCM on its way.

Softtouch; and the rest,
  Tonight I installed a salvage yard ISC nothing changed.
I preformed the self test using the test light method could not get the ISC plunger to retract in test mode.
  Now the odd part, the selonoids under the washer fluid reservoir made clicks. I noticed the vacum operated plunger for air fuel mixture (Softtouch and I have discussed this) had been pulled up by it's own vacuum.
So my belief is that using the test light hooked to the battery did something
I thought I bought a nice car when I bought this one but starting to rethink as it has Gremlins that never sleep.

I have two ISC's  just ohm'd them both one showed half an ohm (0.5) the other had all 0's (0.00) I am waiting for the new ISC to show up I will compare OHM values then.

Softtouch,
  I appreciate the information you have shared a BUNCH.
With my ISC issue the plunger does not move unless I bench test it putting 12 volts to it I can get it to extend and retract but it does nothing on the car. I am beginning to think I need to replace the EEC the only real issue is the car don't like cold starts.
Thanks for the help.

I am sorry about the confusion
I have not ohm'd the tracking switch I have to figure out how.
There is a time delay relay for this IAC somewhere I believe under the dash.
There are 2 relays on a pedestal right side of steering wheel under the dash I would like to know what those are.
The car is running well except cold start that's what I am ultimately trying to fix.
I need to know what powers the yellow/black wire and the white/ blue wire that power the ISC
Thanks for your help Softtouch.

Hello Fox Bodies
I have been researching this issue both on this site and otherwise simple it may be I am still battling it.
So in recent past I was able to extend and retract the projectile by putting a hot jumper from battery to the yellow/black wire and the white/blue wire one extends the other retracts.
This morning I am unable to do even that, I have switched relays around under the dash and still nothing. However my temp gage is now reading straight up the middle as opposed to being on the hot side.
I am going to find some new relays and I have a new IAC coming.
Any advice to Rid of Code 13 and get this IAC functioning would be greatly appreciated.

Misc Tech / Vacum issues 87 T bird 3.8
Since I removed the smog pump and related nonsence the
The heat control valve never pulls off.
How did I loose vacum to it when I plugged the pink and black vacum lines off and directly hooked the green to the egg?
Something is amiss with the selonoids I am just not good enough with electronics to figure it out.

Engine Tech / doesnt idle cold, hard start, IAC adjustment?
I have been having a lot of issues with this IAC, I currently  can get it to retract but not extend by putting a hot jumper from battery to the yellow/black wire and the white/blue wire, Before replacing the relay under the dash I could not get it to do ANYTHING.
I have checked fuses and replaced relays still nothing but Aggravation.

Misc Tech / Vacum issues 87 T bird 3.8
As softtouch  stated it is a method of using the warmer internal engine gases to atomise fuel during cold starts.
Thanks again jcassity
