CAR IDLES AND STALLS on 1999 Ford Taurus

WHEN I START MY CAR AND PUT IT IN REVERSE IT PUTTS LIKE ITS GOING TO STALL, THEN WHEN I PUT IT IN PARK AFTER DRIVING IT IDLES UP AND DOWN AND THEN AFTER A FEW MINUTES STALLS OUT. ALSO WHEN I WAS DRIVING MY CAR STALLED ON ME AND I DIDNT EVEN FEEL IT STALL AND I WENT TO TURN AND MY WHEEL WAS LOCKED SO I EVENTUALLY PULLED OVER AND PUT IT IN PARK AND MY RPMS WERE STUCK AT 2000. THAT HAS ONLY HAPPENED TO ME ONE TIME IN DRIVE, BUT IT HAPPENS EVERYTIME I REVERSE AND PARK. ANY IDEAS WHAT THIS COULD BE?

Have your car scanned for codes. You may have a Service Engine Soon Light on yes? This could be many things, start with a scan and go from there. Which Oxygen sensor ( there are several types of O2 sensor codes, locations, banks etc ) code was it and and what was the Long Term Fuel Trim? An Oxygen Sensor code may be there because there is a huge vaccum leak or a bad Mass Air Flow Sensor, both of which can cause your symptons.

i had that done the only code that came up was for an 02 sensor and the mechanic said that wouldnt cause the problem.
