Sound like you may still have a vacuum leak somewhere.

Yeah, I know. Probably something so stupidly small not to throw a code but enough to throw the car off balance and drive me crazy at the same time. PCV system seems to be in check, had it looked at when the plugs were replaced about 2 weeks ago, also cleaned TB that same day.

You’re the 3rd to point into this direction and could indeed be the problem, that the original vacuum leak wasn’t properly fixed (either bad gasket placement, defective new gasket, etc.)
I have no tools to check this at home so I’ll have to wait until I can take her to the shop when my state reopens |

Do you know if the throttle body was taken off during the original repair? If so the o-ring might not be seated correctly.

So unless the 2 guys messed up reassembling it, I’d rule it out |

Update:
Sorry for not coming back sooner. So we towed her to the shop now that it's open (finally!) but the issue had worsened by now, not only was it giving us the hard starts described before, it was now externally leaking gas, like a noticeable puddle on the floor. Took all 6 injectors to the lab along with the rail, results came as no injector body/nozzle/rail leaks, it was determined it was the o-rings. Changed o-rings to all 6 injectors but it happened again, hard stars and another (smaller) puddle of raw gas after driving her for 5 minutes. The "funny" thing is how one of the o-ring was completely ripped when they took off the injector that was visibly leaking (see pics). Also attaching a vid of the leak, it was on my garage so it was hard to sneak my phone to take the vid without being able to lift her. Why did the o-ring and the white ring were so damaged? And mostly... why the hell it won't stop leaking? https://youtu.be/QHAAFXsH4H8 |

What the actual heck?? Just got a pic from my mechanic?, he was removing the 6 again to check if any other had leaks and we came to find the damn o rings are melted...
Any idea why? I am seriously concerned |

Where were the O-rings sourced? They may not be the right rubber. Or the mechanic had no idea what he was doing and messed them up installing them.

They were sourced and installed by an injector lab (had them tested before to discard leaks from the body).
This set of injectors has been mounted twice: 1- By mechanic A when I had 2 stuck open and replaced the set of six with the orings they came with and failed 2 months later (leaked from top of the injector/o ring) 2 - By mechanic B when they leaked and replaced the o rings Could both have messed it up? What I cannot explain is the melting of the spacers |

Do you know how to identify fake ACDElcos? Now I’m thinking I got ripped off and they’re chinese

I would contact the injector lab and see what they say.
I would probably let the shop who is working on it supply new O-rings, assuming they warranty their work, but you can get a whole set of orings and spacers thru rockauto for $7.21 by felpro (1 left) or AC-Delco for $56. |
