right trying to remember if that has a vacuum operated setup. Some of these vans have a plunger styled unit that connects to the injector pump and pulls and idles up the van, it have a spec to adjust this usually found in your service manual.
my frontier has this.
however i got a few similar problems like this and its the ac compressor that causes this, the compressor was failing and causing alot of load on the engine at idle speeds and low town speeds, had this happen in a zd30 frontier and a e24 maxi already, even caused starting problems too, the clutch started locking up and straining the engine to start.
