since removing the intake manifold to get at that stupid *** ground wire to fix hesitation.

anyways i have increased pedal force to stop and it feels like there is no vacuum assist just mechanical pedal, and my idle is shakey and lower than usual, even with the idle screw all the way up

i double checked all my vacuum lines for the manifold when I put them in and I dont have any missing ones that I can find.

i have feeling my brake pedal feel is related to the illegid leak since the brakes were fine a few days ago but now they feel like ****, but how do I find a vacuum leak amongst a jillion vacuum lines?

 

They may attached, but chances are you brake booster vac. line is cracked. Sometimes with these old girls they get a little brittle.

I would start by running some fresh silicone line from you manifold to the brake booster and see what you get.
