The EGR should be closed at idle and you shouldn't notice any difference, unless the open vacuum line causes a slight idle increase.

ok, thats good to know, ya, i the open vac line causes a slight idle increase, but nothing major, so for now at idle im gonna rule out the egr being bad and focus on the IAC as the culprit and test the 02 sensor....everything else has checked out fine so far,

You should test the egr valve. If you don't have a vacuum pump you can rent one at the parts store.
Also, is the vacuum transducer there? The 89-90 egr system are the only two years they were used. Found mine had got against the exhaust and burned the bottom of it clean off. They are $92 at the dealer, if you need one go Salvage yard.
