Still chasing my bogging down issue while accelerating. Traced vacuum lines, no issue found. I did notice the vacuum canister had three ports but only two hoses attached. Third port is open to atmosphere. I plugged it but it didn’t seem to make any difference. Some diagrams I’ve seen only show two hoses attached. Should the bottom port have a hose, be open or capped? This is the canister behind the driver’s position down low on the outside of the cab. Thanks
