93 Suburban stalling

Help! I have a 93 suburban that stalls when the rpm's drop below 1000. It has been sporadic until recently and now it does it all the time. I can't even drive the damn thing now. I have no clue where to even begin with this problem. Any help would be greatly appreciated.

thanks

It could be a vacuum leak, or the throttle body plate could use a cleaning.

I am having the same issue. Did you ever get this fixed?

After replacing dang near every part of the emissions system, I figured it out. I had gapped the plugs at .35 mm instead of .035 inches. I regapped them and all is well.
