BMW 430i 190302 / 190F08 / 191C02 / 118002 Evap fix

2017 430i Symptoms- check engine light and codes 190302-190F08-191C02-118002 Runs rough on startup almost like a misfire, sometimes ran rough after getting gas The purge valve was replaced and fixed all symptoms/issues. The bad valve would allow gas-saturated air into the intake (causing mixture/rich codes). The bad valve was also not allowing the fuel tank to regulate pressure (thus throwing evap codes also).
