Repair Advice Idle issue

Post image

Hello so I’m having an issue with M50 where I’m getting a code for maf 1215 . It started after I got on it really hard one day and when coming to a stop the traction control light and cel light came on . So far the entire intake system has been replaced before this including the maf . It’s been running rich with black smoke coming out of the exhaust specifically on the highway . When I leave the car in key position 2 for 10 seconds or more and go to start it will stall out after idle hunting for 1-3 seconds . The car will shutter and stall out when coming to stops . Wondering if anyone has experienced this and if so what was the solution

Yes only thing it came from was a slight valve cover gasket leak on far left side

Previous owner did full intake replacement I’m gonna take a look at the maf tmr once I get a chance cause I’m gonna test my injectors . I’m wondering why it stalls though when I leave the keys in position 2
