So when I first start my YJ for the day (4.2 w/ 32/36 weber), she jumps right up to 2000-2500 rpms and runs smooth for a few seconds and then starts to hiccup and become rough. Then when she is fully warmed the idle is nice n' low around 600-700 and smooth. No complaints about driveablilty or warm idle... just the cold start with the choke engaged. she's nuttered...
Anybody know what may be happening?
