Odd controls

[elite marksman]

Yesterday I was told to go around when a 737 landed a mile or so in front of me. After I advanced my throttles too 100% and rectacted the gear, I started an uncontrolable yaw to the right, about 30* per second. I checked the engine controls and both were at 100%, then it stalled at about 750ft and perpendicular to the runway. I cut the throttle and nosed over, managing to get enogh airspeed back at about 150 feet, added throttle again and there was no yaw problem. I went around as the ATC instructed  me to do 2 more times and there was no problems except for the rather bumpy landing due to unfavorable conditions at KBOS yesterday. Anyone have any ideas as to what would cause this?

your autopilot didn't cause this did it?

The other day I took off and immedietely after my wheels left the pavement, my aircraft rolled into a steep turn. After realizing that I hadn't checked my autopilot was off, I turned it off and flew happily ever after

No, I lost my NAV radio about halfway through the approach, so my ILS was out, and I killed the autopilot as soon as I realized what happened. So I went to visual with about 2.5-3.0 miles to go. I slowed it down from 180 to 150 knots to give myself a little more margin of error since it was such an ugly day and there was a plane infront of me that I couldn't see. Ceiling was somewhere around 800 so i dropped below the coulds so I could see where I was going.

What plane were you flying?

Default 737

Try recalibrating your joystick?

Everyonce in a while, my joystick will get out of sync or something causing aircraft to want to bank sharply

Ill try that, but the yaw rate was definatly out of a 737s flight profile, the only way that I can think of to get a similar rate is to put one engine at full throttle, the other at reverse thrust, hold the differential brakes on the reverse thrust side, and steer that direction.
