Unknown Vacuum Leak
 

Hello, I would like some direction with a problem I’m having. Just replaced the coolant pipe under the supercharger. After everything is back together, now I getting P2187 and P2189 with very high LTFT 55% on both banks and the STFT is around 15%. I can’t seemed to find any vacuum leak. I’ve replaced the diaphragm and the orings to the breather hoses. I’ve been getting P0456 for several months. I’ve Replaced the fuel cap with no help and now I’m getting P0442. I’ve done a smoke test too without any signs of leaks. Would it be possible that the unmetered air is coming from the purge valve solenoid? Any help is greatly appreciated.

Thank you,
