1998 Taurus SHO smoking

3.4 V8, Auto trans, 86,000 miles without a major problem until now. Driving started to loose power, SEL came on for a moment, went off and hasn't returned. Borrowed a SO scanner and revealed codes: P0175, P1000, P1116, P1132, P1137, P1138.

Changed out ECT sensor (coolant was green and clear), no change--however haven't rescanned yet--tomorrow. Engine starts up and idles smoothly, for a couple of minutes then starts to smoke (white) and eventually lays down a thick white smoke screen, there seems to be evidence of a fuel smell to the smoke.

Any ideans as to the possible problem and course of action to take is greatly appreciated. Thank you.
