 I bought my Taurus in 2007 with about 40K miles on it. Gas mileage ranging from 15 mpg to 18 mpg. No anti-lock brakes. After about a year I started having problems with the throttle sticking, the car continues to accelerate after I remove my foot from the gas pedal. The pedal is not sticking.  O2 sensors 1 and 4 went out and the car misfires and occasionally stalls when backing up, or during slow turning (like pulling into a parking spot).   I was quoted about $400 to replace both o2 sensors, then another couple hundred to diagnose the other problems.  Car is getting repo'd, I lost my job and cannot afford to fix the car.
