East Central Iowa | I recently had the cadalatic converter plug up, so I thought. I replaced the converter and my Jimmy still ran like crap. (It has the "W" motor). I was told to take the EGR off and clean it. I found it was stuck in the closed position. I cleaned it and worked great.
That cleared the EGR code. Then I had a lean mixture code, bank one, sensor one and the exhaust was stinky. We replaced the front O2 sensor. (This one has one in front of the converter and one behind). Now it is still stinky and the code reads a rich mixture.
Talked to a mechanic releative who said the EGR causes all this... When the EGR sticks one way or the other, it melts the converter honeycomb and that fries the O2 sensors. I don't see how it would fry the one behind the converter though.
My question after all that is... does anyone think this is probably the other $50.00- O2 sensor located behind the converter or could the EGR be sticking again?
Thanks for any help, | |
