Hello new to the JB4 platform and I have been running into some issues recently with the car running rough at idle or at a light and throwing lean and misfire issues. I attached a couple logs one which is map 0 and one that is map 2. Neither map will help the car run like it was a couple weeks ago. I did find that one of my plastic intake tubes that has the single bolt holding it to the turbo inlet was cracked and the orange seal was showing and possibly slid back sucking in unfiltered air. Iíve checked all hose connections and all look tight and in place. I recently installed catch cans on both banks and was in need of replacing the plastic pcv hoses with rubber hoses going to the catch cans. I didnít have any of these issues until I installed these and Iím hoping they arenít the culprit as they are doing their job keeping out the moisture/oil/fuel combo. The car has brand new NGK one step colder plugs, arm intake, arm dpís, bmw 3.5 TMAPS and of course the JB4. Like I said car was running great and making good power with the occasional misfire which is normal Iíve heard for the N63. Hopefully these logs will help explain whatís going on or shed some light on what I can do and also help tune the car for maximum performance. Thanks in advance guys.
