If you've never replaced the rubber boots from the fuel distributor to the intake manifold, this would be a good time. But buy new ones. The old ones have a tendency to get very small, undetectable cracks under the hose clamps from being removed and installed and from the heat under the hood. They're not that expensive. Vacuum leaks will cause the problem you're describing, as well as low/incorrect fuel pressure, which may be the result of the wrong WUR (aka FPR). May want to cross check the part number and be sure they're the same from '77 to '81. When my WUR was acting up, it stumbled on start, would idle but not rev up until it was warm. After that it ran normal. If you can get the pressure checked, that's the best way to diagnose the problem. But even if it turns out to be the WUR, I'd still change the boots. Between the boots and the injector seals, it's cheap insurance on the CIS system.
Changing injectors and injector seals is an excellent place to start. All that kind of stuff is probably brittle with age and heat from being under the hood for 25+ years. The difference will surprise you. You have to be sure there are no vaccuum leaks. After that, you can look to the more expensive possibilites like the fuel distributor, etc. Start w/the cheap stuff.

Has this car been sitting awhile?
