Hi Guys:
|Have a 1990 Olds Custom Cruiser w 5.0 carburated V8. Just had an oil change done at a commercial establishment, and right after noticed a rough idle. Later this evening I started it up, and about 10 seconds of rough idling led to a stall while stationary but in drive.

The idle is still rough when stopped.

Any ideas what happened here?

Thx.
