Yes, reads like a large vacuum leak.
Start removing hoses on the intake and then plugging that intake port, when idle drops follow that hose to find the leak.
Yes, PCV valve hoses on the 3.0l and 4.0l are a known issue, they crack and leak at the elbows, underside where you can see it very easily.

found a crack at the elbow, did lower rpm some, but, still around 2000-2500.
was determined iac valve is defective at this point
what I did for now was made a gasket for the iac valve from a plastic oil bottle and drilled some holes in it and now my idle is about 650 when warmed up, will not idle cold, but, does not take long to warm up
this will hold me over until I get a new iac
