Hi All:
I havew a 90 Olds Custom Cruiser (carburated) - it was running fine until today when I started it and the idle was extremely rough (shaking and rattling whole car) and would stall after being idle about 20 sec. Would also stall when at a complete stop at a stop sign.
Car ran fine until this evening, no sign of a problem. Fuel economy has been poor recently.
Only work done on it in several months was air filter replaced 1 wk ago, and oil change 2 wks ago. Was rough idle for about 2 d after oil change and stalled once the same day as change, but had been fine since then until today.
Any ideas?

Many things can cause this sticking choke, flooding carb, egr valve stuck open, major vacuum leaks.
