If everything else on your car checks out and the problem is still there. Then you would need to install a known good ecu and see if that fixes the problem, if it does then you know the problem is in the ecu.
I actually took her on a 30 mile run yesterday, in which she had a dozen chances to stall and never did. Got a little low in rpms a couple times, but never stalled. Time before that on similar run, only stalled once. Maybe I should leave well enough alone now and maybe ecu needed an adjustment period??

So between last night and this am, she stalled out multiple times at a stop and idle hunted on startup.
I brought her in and mechanic swapped out my recently cleaned ICV for a a good used ICV they had lying around. Out of first handful of stops she almost stalled twice, but since then and 130 miles later, seems to be spot on. Probably had 15 stops in a row that were perfect, and a couple perfect startups. Not sure why she almost stalled twice in beginning though. He said if this doesn't fix issue, then they will swap a dme.
Thoughts on why initially, she almost stalled twice w/ the swapped ICV??

May have been sticking due to lack of use. Once warmed up and moving it loosened up. Who knows?

If the problem persists, I'd check the condition of the reference sensors on the flywheel.

Hopefully that's it, if not mechanic said he will swap a DME in. I'll mention flywheel

Took her on a nice thanksgiving morning run. So nice out in NY, that top was off and people were surfing! Still intermittently stalling, so I would say it's narrowed down to DME now, I'm which I will test a replacement one next week. Happy Thanksgiving!

According to my mechanic and all I've been reading here, it appears widdled down to the DME. However, I'll look into anything else. What's the CHT? You got me there

The DME is under the driver's seat. It is held into place with four 10mm nuts. Easy.

the cht is the cylinder head temp sensor. it is the top connector of the connectors on the left... see if it has one wire going to the sensor or two

I cut a slot in a deep 13mm socket for the wire to replace mine. Loaned it out to a rennlister that never returned it. Made another one....a better one.
