Help - 84 crossfire stumble/stall
After sitting for three weeks, I started my car yesterday and had a problem that I had never experienced before. Above 1,500 rpm, everything was fine. Below 1,500 the car stumbled and finally stalled. Once engine was warm, same problem. I removed the air cleaner cover and it looked like quite a bit of fuel was flowing from both sprayers at idle. The sprayers appeared to flow at the same rate. If this were a carburetor system, I'd say it was flooding. Any thoughts? Fuel delivery, vacuum, ignition control or ???

I started the car again just now. Again, the car is smooth above 1,500 rpm, but stumbles below and finally stalls. I can save it from stalling by giving it gas. One thing I noticed is that if I keep a steady peddle at, say 2,200 rpm, the engine will begin to lose rpm's; it won't hold a steady rpm.
I took off the air cleaner and looked for loose wires, vacuum leaks (hose splits and hoses off), checked the pcv valve, and tightened all of the gaskets in the fuel feed system. No change. Any thoughts? I'm a little stumped, as when the car stalls, it got plenty of fuel going into the manifold.
