Flying in IMC can be very high workload. An autopilot reduces that workload consierably. If you think there is something wrong with it then get rid of it otherwise allow it to free up brain capacity that you can use for other tasks.
The previous post suggested asking an instructor. If you can find one that flys regularly in IMC on an autopilot then good luck to you. There are plenty of exceptions but the majority of instructors fly VFR in C152 type aircraft in their local area and can add very little to this kind of query.
