Any help or opinions would be appreciated. Car struggles with cold starts, stumbles and stalls at idle, crazy fuel rail pressure deviations, -25% fuel trims, and it rarely ever builds boost. I am getting air mass implausible and intake unmetered air faults. I have had this cooper for way too long and have thrown way too many parts at it. All of the parts are oem, I have done a full timing kit w/ vanos solenoid, whole intake system (map/maf, boost pipes, throttle body, intake manifold+gaskets, and intercooler), pcv, injectors, fuel rail, high pressure fuel pump, and diverter valve. I have checked every vacuum line. I’m at a complete loss and I’m honestly about to sell the thing the way it is lol
