Hello everyone, so purchased 2011g37x sedan couple months ago and slowly chipping away at some of the issues. Check engine on with codes p2a00, p0051 and p1168. I do have an exhaust leak. I replaced upstream sensor sensor 1 hank 1 already. It is Admin tuned. Berks test pipes megan y pipe stock mid pipe and revel cat back. Any one familiar with these codes?

 

I’m having code p0051 and p1168 on my 2008 g37 coupe fbo also tuned by admin. so I was wondering if you ever figured it out?

 

Haven't figured it out yet. Actually parked it. No time or funds to fix it ATM.
