    Vacuum going to the catch can and then your rocker cover will be causing a vacuum leak. The diagram shown by Bento should be fine but with the FPR line aswell

    See if the lack of spark is isolated to a particular cyclinder, a good spark is blue a weak one is red. Take the injector plugs off 1 at a time and if the running makes no difference you've isolated your lazy cyclinder.

    Check the dizzy cap / rotor is in good condition. How did your auto electrician do the earths?

    Is your alternator charging? 12v will put in waaay less fuel than 14v.

    Default 16v 4age with itbs misfiring problem, need help

    He earthed everything inside the cabin under the dash, but it was previously earthed on the fuel rail before the new loom, is that a problem?

    I was told the Map Sensor should be a pure signal (by itself)
    anyone have ideas for my setup?

    Your alternator should be charging 13.5 - 14v. Was your issue there before you made your own loom? And was there anything else you changed at the same time?
