1.7 MT. the car started stalling only when I come to a stop when the engine is at operating temp. It only stalls on decel right before it comes to a full stop. I replaced the air filter with a Honda air filter, it seemed to have made it worse (i.e. it will stall on deceleration at like 20mph vs, 5mph, now) I can have the clutch out/out of gear and it will stall, or clutch in/in gear and it will stall. It doesn't happen when everything is still cold, gets worse as it gets hotter.

I took it to a shop, they said it needs a new clutch system.
I called Action Clutch (using a stage-1 for the past year) they said it definitely was not the clutch.
I'm leaning towards the culprit - thrust bearings? Fuel injectors? (original fuel injectors w/ 200,000mi)

Thanks for reading, and thanks for any info.

How is it stalling? Like you shut the key off? Like it runs out of gas?

Like turning the key to off, it'll start back up without hesitation. Doesn't sputter. The car only has a 12 minute commute to work and a 12 minute commute back home. It was happening maybe once a week, it'd be right as i was pulling into the neighborhood. Now, it happens during the drive after maybe 5-8 minutes. It'll be okay in the morning, not okay going home in the afternoon. Heat seems to make it worse.

I'm thinking bearings, I see lots of posts for civic's "stalling coming to a stop" 5th, 6th, 7th, 8th gen civics, autos and manuals, worse with manuals. I likely should try cleaning the IAC, and throttle body, but, I cleaned those, plus the EGR passages - as a PM a couple years ago when I had the intake off to get to the steering rack.

If it shuts everything off as if you turned the key off then I’d think electrical.

that was a description of how the engine stalls, nothing is seemingly wrong with any of the electrics. My battery/alternator/connections/grounds are fine. the engine doesn't sputter out, or try to catch itself at idle, it's /like/ I turned the key to ACC. I could turn the car on right now, go drive it around, and after 5-10 minutes it will only stall when I come to a complete stop, clutch-in/ or out.. I haven't been driving the car since it started happening more frequently as it seems mechanical. No CEL. Which to me says it's going the engine is going to spin a part that shouldn't spin.

Your ignition could be cutting it off. Key cylinders go bad.

Yeah definitely something electrical.
