Default 1990 gmc jimmy high idle

Has a tbi 350 with a 700 r4 tran's has high idle while moving shifter in and out of gear . It will idle about 1500 and does not do it in park only when you move the shifter and no foot on the brake does it as soon as you move the shifter. If you shut it of and restart it usually it 's fine any ideas?
