Describe symptoms>

Code 17= check thermostat and engine coolant sensor ( Not the one for the temp gauge)

Code 51
51 Oxygen sensor stuck at lean position (Bob Lincoln wrote: may be tripped by a bad MAP sensor system causing a rich condition, and the O2 sensor trying to compensate. The O2 sensor may still be good. The MAP assembly consists of two pieces, the valve and the vacuum transducer (round plastic unit with cylinder on top and both electrical and vacuum connections) - If you get hot rough idle and stalling, especially on deceleration, accompanied by flooded engine and difficulty restarting, that can be a bad MAP sensor causing the O2 sensor to try to compensate. If you get poor cold driveability, stumbling and bucking, and acceptable warm driving with poor gas mileage (a drop of 10 mpg or more), that is usually the O2 sensor. [Webmaster note: MAP sensors seem to die regularly

Here is a link that I got this from:

sorry tempfixit, its a 1995 3.5 L 24 valve and it has 161.582 miles, i have replaced the aic, throttle position sensor, but when i first got the car it ran REALLY rough! come to find out someone replaced the coil pack and installed it UPSIDE DOWN! the body and inside are really nice, its an ES, so it has all the little bells and whistles, plus its the little womens car and she just had to have it because it was purple, inside and out : )
