Stumble

My truck has a stumble at around 1000 RPM up to 2000 RPM. It does this while driving and in park. It takes off fine from a stop, but while driving slowly (5-10mph) it stumbles. It's fine at higher speeds, and just started this yesterday. Truck has 305 w/ 2bbl Rochester. Carb was rebuilt 1 month ago. I heard of similiar symptoms being caused by a bad module?? Any ideas?
Thanks in advance for your help!
