It’s not the tfi or the sensor in the disturber we tried a completely different distributor out of an another running

I’d start with verifying the timing and fuel pressure.

Rotate to TDC compression, and verify the balancer is at 0/TDC to see if she’s slipped a little. If that checks out, pull the spout connector and get a timing light on that thing.

I cants recall the fuel pressure because my brain doesn’t work like it used to. Something around 40psi. On the low side with the vacuum hooked to the regulator. I like to rig mine up to watch it under load because revving it doesn’t ask for that much fuel.

It is sometimes wise to remember that new might not mean good.

Did the timing when we did the distributor so I don’t think it can be that. Haven’t done fuel pressure yet but your right, right around 35-40 psi. We’ll definitely try fuel pressure underlowd cuz it likes to stall even in park

Also too add did the seafoam trick in the vacuum line after that it did this worse

You set the timing with the SPOUT connector out? It won't be right otherwise.

10 BTDC is what it wants. Make sure you don't get 10 ATDC. I did that once, it ran like shit.

Check fuel pressure. 30-35 with the vac line on, 40-45 with the vac line off is about right.

Check the vacuum lines too, any bad ones need to be replaced, especially the one to the MAP sensor. Also check it for codes if you have not. If the TPS is a dud, it will act stupid but it will set a code for it.

Yes spout is out when we did the timing haven’t done codes yet but that’s next on the list. Usually the tps woudlt do this that severe

What the gadget and Tig said.

I once pulled the dizzy on one of these and put it back a tooth retarded. Started up fine but would not rev up or even move to save it's life. THe fellas on here helped me fix my stupidification and the car was right once again.

Seafoam is snake oil, it'll clean fuel infectors fine I'm sure but all that smoke you're seeing is the mineral oils within the stuff being burned. I've seen more than enough videos where they scope the combustion chambers before and after seafoam and the results are negligible. If put in the oil as suggested though, it will free sticky lifters and such. That much I believe. There are other methods to doing that though too.

Still stumped anyone have any ideas, computer maybe?

+1 possibility the distributor is mis-stabbed.
+1 pull the codes, they may not tell you the problem but will guide you towards it.

Do you have it wired for the correct firing order, which is noted on the sticker on the cooling fan shroud?
If you are using the Mustang firing order you may have found online, it's not correct for our cars.

Does the engine run OK with SPOUT disconnected? It will be short on power because the computer won't pull the timing, but if it at least runs properly, that's something worth knowing.

The ECM rarely goes bad. Its not impossible, but its definitely not the most likely thing. They also tend to give wierd codes, no codes, or have some other sign that all is not well.

[sly]

like producing magic smoke... like the original ECM in the Mad Marquis I used to have.

[gadget73]

yeah its not impossible for them to fail. Its a 30 year old electronic gizmo that lives in a torture chamber. Its still a fairly reliable device tho. I re-capped the one in my car because it was obviously oozing goo out of the caps, but it was working perfectly before I did it and still does.

Have you pulled and checked the spark plugs? They might all be fouled and shitty. Just a thought and a cheap, easy fix. Not a bad idea anyway since you don't know when they were last changed.

You don't mention what you did with the cats. Remove them? Replace them? Left them alone?
If they got doused in fuel for long enough they may be plugging up, and in turn that is hurting your high rpm, as time goes on it just gets worse overall.
If you left the cats on it, disconnect the exhaust ahead of the cats and take it for a test drive. If it runs right you got your answer.
