[QUOTE="FordTechOne, post: 1682943, member: 35543"] The device is an aspirator, the PCM controls the solenoid valve to allow vacuum to reach the booster. According to WSM it is activated when booster vacuum is low to provide additional vacuum. So I suspect it’s normally in the closed position, restricting flow. This might be a stupid question, but the check valve is install in the correct orientation right? I haven’t heard of repeat failures, that is strange. If the booster is losing vacuum after sitting, that’s either a bad booster (leak) or a faulty booster check valve. Have you taken vacuum readings at vacuum supply line (from engine) at idle? [/QUOTE]
