Go to www.google.com and type in your code and search for it. A whole slew of links will come up to tell you what it is. I'd suggest saving a few of them as favorites so you can refer back to them when the need arises.
so i pulled the codes and it came out as PO136 which was Bank 1 Sensor 2 downstream O2 sensor. so my question is, which side is Bank 1 and is downstream the O2's with the MIL eliminators on them? why would this be happening if i have MIL's? could it just be a bad O2 sensor?
