Any DIY on it? Any other way to check on it even if you don't have the special pressure gauges?

Spray some carb cleaner around all your vacuum connections and where the intake manifold meets the head. Take your time doing this. When you spray the cleaner on a spot and the idle really surges, you probably found your leak.
