I recently had some post-cat o2 codes, but I've replaced them and now have no codes on my cheap OBD reader - definitely wouldn't show all the same codes as a durametric.

After the stall, it struggles to start but the rpm meter does bounce

Also recently realized the previous owner had drilled holes in the aos - I assume to relieve pressure after failure, so I've replaced that with no changes to the issue.

I've also unplugged the MAF and restarted the car, but had the same symptoms.

Could someone point me in a direction to start a diagnosis? I can't find many examples on the forum where it only stalls when warm.
