On my way to work today in my '94 YJ 2.5L, I came across the problem of where I would be maintaining a constant speed and the engine would hiccup and start dropping RPMs while I maintained the same position on the gas. It would slow from 65 down to 55, but it would do it in steps where I'd feel the deceleration but then the engine would kick in again. When I got home I checked the engine codes and got back 12, 33, 21, 52, and 55. 12 being the battery was removed recently, 33 being the oxygen sensor or circuit, 52 being a rich oxygen condition, and 55 being the end transmission. I was wondering if anyone had encountered this with their YJ and could recommend a fix.
