I have two error codes on my 2005 MCS.
1) The first one is P2098 which is a post cat long term lean condition bank 2
This error comes on with SES light. I can clear it, but it is hard coded in the ECU so comes back the next time the car is started
2) The second one is P1498 which is unmetered air passed the compressor. It comes and goes and always clears after the next start. It causes the EML to come on

The P2098 is a vacuum problem I think and the P1498 is a pressure problem after the compressor. Are these two errors related and why do they cause two different error lights

Any suggestions on how to fix both? My thought now is to replace the vacuum lines and rubber and plastic intake system, the intercooler boots, the MAP sensor and hose, the green supercharger gasket and anything else you can recommend.

Any help on this problem because I am tired of having lights on and losing gas mileage
