As far as i know it does. The OTC does a complete advance scan and actually advances and retards the timing in sequence. As far as static timing goes remember the ECM used the DIZZY for TDC location. Another words it looks at the PIP to determine injector pulse or discharge timing. So if to far advanced and or retarded the fuel tables are delayed or advanced with static. Been messing with this on the MIDNIGHTER. It is extremely sensitive and makes a big difference.

That explains why when I turned the dist one way, I could get it to run decent at lower rpm, and bad at higher rpm, and vice versa.

Gimme a 302 any day..

You should also check to see if you have a cracked spark plug

How to exactly check for that issue with this type of problem is kind of beyond me

The easiest way is to use a timing like to see if the light is stroking Steady or if it jumps around


I still have the very same issue you're describing and I've not narrowed it down yet

Also with the TF I removed probe the black wire connector of the stator with your ohmmeter and place the other meter lead on the distributor chassis and check for 0 ohmes
The black wire of the stater will be soldered to the stater mounting bracket inside the distributor and aftermarket does a poor job of this important connection
Add a temp wire from the tfi harness black wire to dizzy chassis and see if the issue improves

I'm re-re-pulling plugs and swapping the plug wires probably Sunday. I work the rest of the week, 12 hour shifts, so no car time this week.

I would think, a broken plug would be an issue all the time, not just sometimes to where it happens, then restart the car and it isn't there for a while. I have no idea. After plugs and wires, probably taking it to the shop.

Once the kiddos are in bed, I'll pull the EEC and get a pic of the code to make sure it's what will work with your setup (though I'm sure it's an A9P, '89 Stang, AOD trans.)

I'll shoot ya a text in a few so you'll have my numerals again ;)

You and i have had the same issue that occured around the same time.

i am still sucessful in making it go away and come back like i described on your other thread but........... i did initially throw a TPS at it becaue that is what it "felt" like.  it happens at a consistent low speed while possibly in 3rd or od, and while i am lightly on the gas pedal.

I pulled my codes and focused on the EVP and the solenoid that controls vac to the egr,, you dont have an egr, i do.
for what its worth, i have no friggin clue what this is but i want it gone badly.  When the wifes Ghia is out of the stall, i will work on this some more.
sorry no help here, hope you figure it out.  the codes i get really dont tell me where "I THINK" i should go but ikeep believing my eec.  I can throw spare good parts at it till the issue is gone but like you its an issue that only crops up after the engine is warm.

question for you though and im interested in your response....
~have you noticed that when you first start the car and lets say you drive a short distance somewhere , turn off the car, then in short order you start up again and during your second time in the car , does it seem to show up then?
im seeng this on my end.  Initially even after warm up it rarely shows up, it will always show up the second time i get in and start up.

Yes, that happens at times. Initially, drives great, after I stop and start it can happen, but, it also can happen without stopping the car. Not long after I drive it a short distance.
