Seafoam not flowing down
The air pump's working since I can feel the airflow after I disconnected the hose. But the seafoam stayed in the hose after even 3 5-sec cold start. I left the seafoam in the hose, drove around, parked around overnight for it to soak in, but the seafoam's still mostly there the next day!
Does this mean I have bad valve or vac line? How do I make sure the seafoam gets in to rid the likely blockage before I can diagnose other issues
