Anyone have a problem with this O2 sensor by chance ?? Ijust installed one along with a new engine and I'm getting a bit of a hunting idle at times along with smoke.....tons of white blue smoke. Also pulled my plugs after only a few hundred miles and the are black sutt indicative or running super rich. Anyone ??

 

I installed mine awhile back when I put in the M2 DP. I really didn't notice any difference for better or worse but my OEM only had 42K on it.
