Currently at Idle I am seeing -9 vacuum and idle search. Once warm the idle search stops and my AFR's at idle are 10-10.1 rich. Low vacuum continues. Runs 5psi boost fine with good AFR's. Rich at the top RPM Range (5-6k).
5 pounds of boost
EMB piggy back
Maf still connected
External Wastegate w/ TIAL BOV
PCV removed/vented and gasket cover to air, intake side plugged (Don't know why)
Intake at turbo/filter plugged, gasket cover to air (Again don't know)
Hooking pcv valve and turbo side intake back up to gasket cover (no change)
Checked over and over for vacuum leaks (carb cleaner, checked connections)
Things haven't done:
Checked injectors for leak/seal (took injectors out and cleaned previously)
Installed a Megasquirt
Replaced stock o2/ wideband o2
I am looking to get the Vacuum in line and understand or fix the rich idle. Seems like they could be related but may be way off base. Any help would be much appreciated. I was not the original engineer of this turbo setup. Thanks in advance.
