You didn't say what year it was.I remember a BIG number of these engines with a defective fuel injector in the mid 90s.(if shooting carb cleaner in the throttle body straightens it out,this is probably your issue).This engine had an odd setup--there is one injector with 6 nozzles on it,and out of nowhere one bank of the engine would get no fuel.(The "spider" injector is inside the intake manifold).

There is a "spider" injection system in the intake manifold. Check that.

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

could be a clogged fuel filter. How long since you changed it?
It is located bolted to the frame on the drivers side. They only cost $7.00 so I would try this.
