Wanted to know if anyone might have a idea on what wrong with my car. I'm getting error codes 13,32,43,54. Also now when i turn my car off, it will kept running for a while before it stops. Right now I am trying to fix the O2 Sensor. I have tested the voltage at the connection and it reads 1.508V output on the ECM side.. The computer read of the 02 sensor is 453mv. (doesn't mater is the sensor is hooked up or not). I have tried a different computer same thing. (The new computer did fix the the fuel pump relay). Any advice is welcome, I have been working on this for about 2 weeks now.
