I finally fixed my flare problem. My 190 was so bad that it would snatch my girlfriend dress right off after every date, HAHAHA. I replaced the Modulator vacuum rubber hose and adjusted the Modulator with the T shaped key (turn clockwise) behind the rubber cap located on the Modulator. The Modulator is located on the left side of the transmission right over the main plug.
Note: The vacuum hose is hard to replace. Your best bet is to use to pair of needle nose pliers.
Hope this helps
