few probs

Basically I'm trying to sell my winter beater so heres a copy and paste of my ad, what am I looking at to fix these.

The AWD has a vibration/shaking on low speed corners, such as trying to make a U-turn. Other then that on the highway its perfect. We recently just put the fuse in to disable the rear wheels to make it FWD Only right now and it runs perfect. All you have to do is take the fuse out and its back to AWD.

Every once in a while it will take a few extra tries before it starts, once it does revs a little high, but then goes back to normal. It always starts no matter what though. Probaly just needs a good tuneup

The low speed studdering is the torque converter (assuming you have an auto)
Either way, change the rear differential and transmission fluid and add some Lubeguard. Should clear up the shakes.

Good tuneup should help with startup (air filter, fuel filter, oil, oil filter, sparkplugs and plug wires) Check the vacuum hoses (black hoses connected to the intake and throttle body) for any cracks or leaks
