One actuator closes faster and easier than the other.

I just put my manifold back together and the right actuator would take more pressure and longer to close. So I took it apart and put the vaccum lines on (just the r-actuator, not attached to the manifold) and the l-acuator attached to the runners and the pleneum. I attached the vaccum lines and used **** suction to close them(please no jokes). well they both closed w/ ease. So I put them back in and now the right is slower and takes more pressure again-(about one suck). Is this noramal?

Sounds like you have either a small leak or a restriction in one of the lines.

The valves close by vacuum (vacuum is not pressure, but the abscence of it) and open by spring force. The springs are internal to the actuators. You should check the linkages for friction and maybe even put a drop of oil on the throttle shaft. The butterfly valves should move freely with the actuator disconnected.

Or, as mentioned previously, there could be a restriction in the line to the diaphragm actuator that is not allowing the vacuum to be released quickly.

Well, there is no restriction in the line because with the secondary off of the runners and pleneum they both close at the same time with the same amount of vaccum. What I did was attached the T-hose to both the actuators and used my mouth to manually creat vaccum at the leg of the T where it connects to the sensor on the back of the manifold. Just like it would if the car was running. Well I wd40ed the moving parts of the right actuator and still there was no difference. The question is though, would the right needing a tiny bit more vaccum to close affect if the butterflies would fully close or not? I am going to be testing the sensor and signal that control the secondaries today. What would be the part # for that small vaccum canister on the back of the intake and that small sensor? I am really trying to solve this problem, since ford won't. thanks a million guys. I owe you guys a lot. hail
