since you are unable to perform engine running codes and you dont have maf or fuel trim codes

And you can keep the engine running with throttle


airflow is still on the table, dont you think?

I think that would make sense, yes.

Which makes me think IAC but we already ruled that out, right?

 

[indy2000]

IAC works, yes

but what controls IAC?

 

[TheZ06andFoxbody]

IAC works, yes

but what controls IAC?

The computer? Or a relay or vacuum line?

ECM

ECM

Is there anything else it could be or is there any way to verify before replacing it?

 

[indy2000]

We could not call the ECM, until you can verify the inputs, and power and grounds to the ECM are good.


Since you said it can run with more air, should we not try to retrieve running codes at warm temp, ie keep it running on its own at temp, by increasing airflow at temp

what do you suggest do to get more air while at operating temp?

Verifying the inputs/power/grounds is a little above my skill level unless someone can tell me how to do that.



The codes I ran were with the engine at operating temp; I held the throttle open to keep it running to get it there.

so I should run the KEOR codes with the throttle held open?

drove like a turd, had all the typical symptoms, you just didn't mind it

you probably carried a spare TFi, flatblade so you could adjust things that are not adjustable

flat blade for what? adjust the stop screw?

The caps in the EEC are easy to check by removing the cover and inspecting. The caps affect the fuel pump and align pretty well with your symptoms.

a wideband would tell the story.

The capacitors? Would I just be looking for somethingthat visually looks fried or damaged?

look for corrosion from electrolyte around the base of the three electrolytic capacitors.

the codes you posted, does not specifically say engine running or off

do engine off
list them

then engine running

list them

the story that 32Vpwr has no idea how EFI works

yea that story, gotcha

 

[32Vpwr]

lol. no idea at all. keep chasing the "air pedal".

 

[indy2000]

lol. no idea at all. keep chasing the "air pedal".

thanx for your admission, just it case you didn't know the throttle ONLY controls AIR


only chasing the data the testing has shown, something a parts thrower like yourself wouldnt know about.

 

[32Vpwr]

its comical. what r u going to tell me next the brakes are only for stopping? lol
