My MPV does not idle properly. It seems to be related to a moisture problem. It happens primarily in the morning when the car is cold. I read the fault codes and got the following: 1) P0442 - EVAP Emission Control System Leak (small), 2) P0441 - EVAP Emission Control System Purge FLow Fault, 3) P0456 - EVAP Emission Control System leak very small, 4) P0505 - Idle control system malfunction. I'm hoping these are all related to the same problem. Any ideas?
