Long story short, I inherited this car from a family member. Has some issues like a non-functional speedometer but that's easy to work around. The car sat for quite some time but I got it running and I use it to drive back and forth to work.
I'm getting intermittent surging when I'm around 30-50mph and the car will low RPM stall if I don't give it gas while stopped. Any ideas what could be causing the issue? I don't know much about cars but the Internet is telling me to check IAC, EGR, and fuel pump. My sister's boyfriend helped me quite a bit with it; he said one of the vacuum lines was cracked but he fixed that.
It's really not a bad car (~90,000 miles) and I can drive it, at least the 2 miles to work, back and forth everyday; it just stalls at lights and I'm already a severely anxious person when everything is working right. I'm not in a position to do much at this second but I can't imagine threads move quickly here; I can look into whatever is advised when I get home in about an hour.

Take off and clean throttle body and IAC
Not that hard usually but I don't know how difficult it will be for oldsmobile.
If it's intake manifold/egr clogged then you might need to take to mechanic instead
