I took the advice from somebody on this forum and just did away with the black box on the valve cover. I just bypassed it by plugging together the lines that went there and came back to the same place.

Now I have absolutely no power.

Trans shifts early and I never get up to speed.

Everything was fine until I did the vacuum line switcheroo.

I was under the impression that I could reduce my risk and simplify things if I did this but so far that has not been the case.

Should I just hook it back up?
