Remove the vaccume line to the EGR valve and see if it still does it. It may be a bad EGR valve.

Fail smog for high emission


you need to do a major tuneup !!!!!!! replace air & fuel filters, spark plugs & plug wires, distributor cap & rotor, replace OXYGEN SENSOR, change oil & filter, hopefully your catalitic converter is ok, if not , it should be replaced !!!!!!!!!!! together w/tuneup would be the best way to assure passing emissions !!!!!!!!

Try new distributor cap and rotor. I had the same problem on my 1995 4x4 2500 Suburban. I just did a complete tune-up and solved the problem.

Hope that will help.
