check engine light

[tkrug685]

i just changed my o2 sensor and my light is still on do i need to reset the computer?

Yes.... you'll need to have the error code in the ECM reset. Anyone with an OBD-II scanner can do the same for you!

if you cant locate a scanner, just unhook your negitive battery cable for about 10min, then start it up and allow it to run untill its at operating temp, then drive it normally for a few miles to help the fuel trim adjust, after that it should be fine.

I messed with the cats and the sensor was messed up I was told to pull neg off for 15 min and it would reset the comp
