Another video today after parking the car for 1 hour, it gets worse and worse with the hot weather, the noise in the mid of the video was the radio 😁

So now im really thinking about the fuel pump ( maybe its the beginning of a fault fuel pump)

Or sparks or throttle body emmmmm

Based on your diagnosis, sounds like a Possible failing Crankshaft Position Sensor.

Since starts fine when cold, fuel pressure is on the rails

like i said gonna need to put a scanner on it and see what its doing, unfortunalty u are just wasting your time asking people here, anything is just a guess. I can tell you it has nothing to do with the starting system, battery, cables or starter.

need to monitor fuel pressure, spark, crank rpm etc when it is happening and see if one of those is dropping out. if the engine is getting flooded when sitting or if the throttle body is going crazy.

Hi guys back again with the solution for my problems , after searching and alot of diagnostics, i found the solution by changing the purge valve and fuel regulator , also i got much more power

Before solving problems 0.8 bar

After replacing the parts 1.1 bar

Hopefully this will help someone else

Thanks 📣📣
