I keep getting a 0031 trouble code. I seem to have lost my book so I nether know the cause of the code or what the code is. Any help would be greatly appreiciated.
are u getting the code too or no? if a cylinder is just running rich all the time no matter what it could be something as simple as a leaky injectorI am now getting the same problem with my car, but the trouble coming up is just telling the car is rich not that the o2 sensor is bad.
