Wont idle after vac delete

88dx just vacuum deleted the black box and most other lines. Also deleted most coolant lines to the intake since they rusted out on my car. Car won’t run unless I keep my feet on the gas. I’m assuming a vacuum leake somewhere but how can I check if I can’t keep it running long enough to spray it with brake cleaner to hear if the idle changes. Anyone else have this issue if so how did you fix? I’ve turned the fuel mixture screw all the way out and followed the vac delete guide with no success.
