I picked up an 84 cutlass with a sbc 350 and a th350. Everything was fine for about a month. Last couple of times I’ve driven it it stutters and sounds like it’s going to die when I’m at light. The idle speed goes way down to around 400rpm, loses some of the thump from the cam. Unsure of what the issue is. Maybe bump up the idle speed on the carb?

Check for vacuum leaks first. Work on what would be simple fixes first to find the issue.
