some updates, and some new problems

1. a couple of weeks ago I replaced the fuel accumulator and fuel filter at the same time, the car seemed to start somehow better (but hard to tell tbh)
2. yesterday, a friend and I, replaced the fuel pump (URO or DANKS can't remember, that came with a new check valve) because my stock pump was super noisy (loud buzzing) also I wanted to be sure I checked all the boxes of the hot start problem.
3. right after replacing the pump, the car started immediately (of course after a few cranks waiting for the fuel to fill the lines again)
4. we ran around for a test drive, we stopped for pizza, then for gas, and all went well. the car seemed to start well and finally no more noise! no sputtering, no gas smell.

now today I started having a new problem:
when I start the car, it has a rough (shaky) idle/low rpm and I need to let her warm up for 20-30 seconds, then I can give gas and then run.
If I press gas right after it started, like I would do in normal condition the car dies. so I have to wait 20-30 seconds than gently give some gas to "warm it up" than I can drive around and the car keeps perfect 1,000

after I start and run, the car goes very well... it keeps 1,000 RPM super steady at idle.

now... I understand someone may say "You should have bought Bosch" parts, but I have a hard time believing the quality is that different as they all are mad in Europe...

what else can it be? maybe we didn't tighten enough the lines? the URO pump come with a faulty valve??

the only part that is old/stock at this point is the starter ( but I don't believe is the problem), and the O2 connector which was falling apart last week but I guess I would have had the issue before replacing the pump

here is a video I took today of the start/idle at idle below 1,000RPM, the video was shot after stopping only fro a minute after a longer drive so in this specific case the car starts immediately
(what is the noise/ fart sound right after the car starts at 00:02?? seems form the back)


to recap:
- car keeps perfect 1,000 idle when driving around
- car starts immediately if I stop and go for gas or super short stops
- car start having issue when I stop between 20mins or an hour
- car doesn't seem to have some issue if I stop the entire night or few days
- despite replacing accumulator,pump and check valve the car still needs more cranks if it's warm
