Default Drivability issue when 89 SPG is cold

Hello, I'm finally back in my SPG after 7 months. I've replaced a ton of stuff so I was hoping the car wouldn't give me any grief, but it is.

When I first start driving the car, the car lurches, it wants to stall, poor throttle response, etc. But after about 1-2mins of driving everything settles down and works well.

One thing I know is that my AIC is broken (I've cleaned it and it still won't repond), this is probably giving me my high idle as well (1500rpm).

One of my guesses is that the o2 sensor preheater circut is faulty causing my mixtures to go wonky until it warms up. The sensor is brand new though.

Any other insight, tips, solutions?
