Fitech idleing issues

Ok I think I found my dillema! Did rechecked the pcv valve and is operating correctly but noticed I hooked up the brake booster vacuum line to the drivers side valve cover for some odd ball reason. Capped that off since I'm running manual brakes/no booster and... it's actually idleing great and stable. I can't believe I did that! Wondering what the heck I was thinking there. Gona Drive it some more and see if this problem comes back. Did spray around the fitech base as well as the intake and no change so I'm gona rule that out. I'll go ahead and join that Facebook group you mentioned wireweld. Yes it's a devided intake plenum, thought about putting a pneumonic spaced in there but if the problem comes back I'll fiddle around with that as well as Koop rate and such!
Excellent news!!! Good luck man!
