Vacuum leak!!! Rought idle!!

just replaced all my sensors in my 87 it's running pretty rough when Its in idling. Narrowed it down to a vacuum leak. Now I can't pin point it, how can I find it without a smoke Machine?

Why not just spray around suspected areas with an oxygen sensor safe carb/throttle body cleaner?

Have you checked to see if your intake manifold bolts have loosened?

If you own a Renix Jeep, you'll want to check this out.
