Just check your car does not have differential locks, in theory they should not come on without being switched on but they can fail in the 'on' position. Lift both front wheels and see if the steering is stiff with the engine running, if it is then the 'locker' is not to blame. If it is now free then look at the locker and see if it has seized,

these were the best engine ever built by Toyoya they always had a tendancy to do this ,make sure all the vacuum lines are connected nand the idle should be set at 800 rpm. you seem to have to give them a bit of revs to over come the problem
