I'm getting a constant P1127. VagCom reads my numbers are out of spec, only at idle, and it was BARELY off, so my "leak" is coming from right after my throttle body. Checked, but found no leaks, so my next area to check is the PCV flow, since the MAF, plugs, wires, district/cab, filter, coolant temp sensor, etc is new.
Previous owner installed a BFI valve cover, with the two bungs. Had a line running from the crank case, to one of the bungs on the valve cover, and another line from the intake, after the MAF, into the second bung on the valve cover.
