Evap Valve clicking with codes
 

P0102 Air flow circut low input (Probable cause Large vacuum leak)
P1137 Fuel system too rich (probable cause purge canister valve stuck open)
I noticed after getting these codes that my EVAP Valve on top of the airbox clicks constantly, is this normal? This could be the cause of the 1137, but would it cause the 0102? I also am aware that both these codes relate to the MAF, but since the EVAP is clicking contantly I am wondering if this is the issue. Anyone have a similar issue?

no one?
