So Both Connectors jost the connectors take ventilations from the Inside? Wow amazing. So just to double check I found the DIagrams!! 1 The Line that goes to the Filter is also conected to the vaccuum transducer, exhast gas recirculation valve that goes take air from the Inside. The question should Be How many Inches of vaccum shoul I have depending which valve Am I using? because my problem I think is that there is not enough fuel delivery when the Turbo enter in action. What I am Having is that the car accelerates well good (could be better) but lets say that it is on second and when it reachs 40MPH and 4000 RPM or 4500 RPms, It stays and does not get any more MPH and the reading on Turbo was 9 LBS. What could be the reason? I do not want to play with the ALDA but makes me sounds like I will.
