Honda accord stall when at operating temp

I am working on a 1997 honda Accord sedan with2.2 single over head cam non vtec engine. The car had a bad miss that turned out to be a bad intake gaskets. We replaced the head,intake,exhaust and plenum gasket. The car ran great till it warmed up and I snaped the throttle it reverse and came to a idle and died. The car would then start hard by feathering the throttle. I went to lunch and it cooled down and when I got back it fired up and ran great till it got warmed up and then same thing. I checked the egr, iacv every thing it with in the values of all data we even pulled the egr plate and cleaned it up and checked tps it values we also good I am out of ideas any help would be great opportunity and replaced the key swith and checked main relay

Was the head check and machined? Even if so I suppose it's possible to have a flaw or any other part you worked on or might have missed. Re-diagnose as it this is a new problem paying attention more IMO to what you just did,

The head and block deck were straight Edge checked and we're with in tolerance. The intake also was checked I was a diesel tech for 25 years and have access. To alldata that's ware the values I got came from tested old school with a multi meter I have a small matco reader but can't do engine running scans

Wonder what fuel pressure is doing when the engine stalls and has a hard start?

The fuel pressure was with in its range with the regular un hooked and hooked back up and stayed at35 when it was warm and stalled

How does it run off idle, cruising, and accelerating? Does it ever stall other than at idle?

Back to the head. Why was it changed and only checked with a straight edge instead of checking it out? They are as frail as can be and hide cracks that would change when temp does and not be seen by eye so easily. Guessing it was used right? Maybe that's why that vehicle was scrapped to begin with?
? IDK where I'd start first. I think I'd look for plug uniformity if just one show unlike the others and go from that,

It has not made it on the street because when it heats up you have to keep feathering the gas

It's the same head that came off we changed the gasket I also used a the part spray cleaner a dye penitrent and a developer and it showed no cracks it a process used to find cracks in high pressure hydraulic parts

When you state you have to feather the throttle to keep it running, how does it run. Is it running rough or skipping while your feathering the throttle or does it sound fine but just doesn't idle?
Just trying to figure out if this is an idle control type problem or something other than that.
Have you adjusted the valves? Honda's are sensitive to manifold pressure.

So this is to say you've never driven this car on roads at all? Did you get it with the problem and YOU diagnosed the gaskets you replaced? Was this a wild overheat or an IDK just had the symptoms?
Back to top post and subject line suggests it runs fine till warmed up. To me I'm just stuck on thinking a total stall is it just can't overcome ordinary reasons for lowering RPMs to which there's a limit. Say you have A/C on, steer the car both are loads compensated for but not just warming up and if fact you say stalls out.
Compression OK and even on all? Vacuum reading at idle correct (~18Hg or so at idle and the same at ~2,000 RPM) would indicate general engine health. If not a serious vacuum leak even just the wrong vacuum hose could send it all off.
It's back together again now from the work so I'd do the tests again for each cylinder being even enough, compression enough and even try pressuring up each cylinder on TDC for a leak down if so and where it goes.
It's OBDII, codes would help. It's forgiven for some things when just started then when it closed loop can't hold an idle when controls tell it just exactly (best it can) fuel delivery, timing and more for max efficiency and performance. If wrong info gets sent it would mess up.
There's only so much time cold and for testing but I might try fast cylinder balance if nothing better available by cancelling one plug at a time and it shouldn't stall when cold in this case IMO and run equally lousy with each cancelled. If one goes totally or close to dead when warm it just might stall out missing ONE cylinder? If random another reason to chase.
Sorry if a goose chase but I don't really trust that cylinder head yet. It wasn't redone just straight edge checked so right now only you know what it might have been thru to need anything at all to begin with,

I adjusted the valves when you hold on the throttle a little it seems to run fine then when you let it go it idles rough and misses and shuts off I just ran a vacuum check and it only pulls 12 inchs of mercury when it hot I think I am going to have to build a smoke machine and try that

12Hg suggests you are checking at wrong spot, super high altitude or valve timing off which may explain a lot.
Hg for an engine at idle at sea level could be 18-19.5 or so. Each 1,000 ft of elevation you drop that norm by 1 Hg with all things equal.
About now valve timing is my guess. Off so all would be off equally. Do check that with known actual manifold vacuum "T" line in so item a vacuum line goes to still operates or test is not valid,

If the engine is running badly with the throttle closed, it is going to have higher manifold pressure. That is going to be a effect and not the cause. Even with a vacuum leak the engine will run better at higher rpms and will rev up just fine.

The car came with this problem it my son's project car we had a oil leak that we thought was the head gasket that's why we replaced the gasket turned out the oil leak was a sender in combination. With the rocker cover . The stall is a slow stumbling stall we checked compression. It was good just did a vacuum and it was only 12 inchs of mercury so it looks like I have a vac leak some ware looks like I need to build a smoker

Okay just got in from the shop we let the car cool down and went to start it it fired right up a ran smooth so I turned on the lights air and anything I could power up. the car ran great no trouble so we left it run till the fans kicked in still ran great so I hooked up vac gage had 18 inches of mercury on the gage which is normal still running great told my son to give it gas he raped the throttle twice below 3000 rps and it recovered and ran great he did it a third time over 3000 and it started to stumble and died thinking that.tps maybe

! I don't think you are properly equipped to work on this engine to this level without a lot more equipment and exact diagnosis and understanding of this exact one.
Reading between the lines, typos and all you've torn this down for a leaking oil pressure switch........
For that you decided it needed a head gasket job!
That one perhaps, hence opening Pandora's box of problems now throwing darts at the guess board of possible things. I don't know how or where you tested vacuum under what conditions but hard to see a real 12 Hg and have good compression if checked properly. Just for good measure what do you consider good compression? What were the results? What did the plugs look like? I've asked you that before without an answer.
Now it must be a TPS - maybe? Why guess when you could at least do a test on it?
This is a pretty high strung engine that wants plenty exactly right and not very forgiving.
There must be a lot of bucks already spent at a glance the full head gasket set was up there alone never mind new head bolts you didn't mention if new or not another $100. If new is not required it does need each one totally cleaned and oiled (as per a quick read on this exact one) or torque would be in question.
IDK - What do you want to do with this thing before it's declared not worth fixing this one up vs some other vehicle to "learn" on? Any mistakes seem to just set this back to worse,
