31 Code On 1989 Corolla 4Af Carbureted Dx

Hello,

I have a corolla with 59000 origional miles on it. I put cap, rotor plug wires and plugs on it ,10000 miles ago. Recently I had a stumble miss while accelerating and a "Lopy low" idle when in gear and engine cold. I pulled the codes and got a 31 and 41. I replaced the Throttle Position switch and that solved the acceleration miss but I still have the Idle problem. I also sprayed carb spray around the vacum lines and engine but no noticeable change in rpm. Any ideas would be appreciated
