Message	okay so yesterday i posted about a problem with my z hesitating horibly at idle, and acting erratic. all of my symptoms are very comparible to a bad o2 sensor. i ran a diagnostic today and was shown a code 33. the car stumbles so bad its almost imposible to keep it at 2000 rpm so i cant tell if the light is flashing, staying on or off, but the car smells so strongly of gas that i believe that it is def running to rich and the o2 is failing. heres where i need some input. im not sure if the sensor is bad and causing the rich running or if the sensor is just cached with crud from the car running rich. how can i lean out the car to see what is causing the problem
