no codes as I have erased the computer codes and have not been able to drive it, the only codes that had come up were o2 sensors downstream, and i have changed those so i erased them, so as of right now no codes, how long does it take before the rover will throw a code?

 

That will depend on the code. Some are 1 time, some must happen on two or more "drive cycles" before they move from "pending" to check engine light lit up.

 

okay, it finally threw some codes, here they are 1316, p0300 p0451, ugh,,,,, help thanks guys
