Rough running.

I have a 1990 Serria, two wheel drive, with a 305 motor and it runs well on the highway but terribly at a light or slowly into my driveway. Changed the plugs, the wires are good, changed the fuel filter, sprayed carb cleaner. I'm running out of ideas.

Do you
have the same problem?
Yes
No
