Question about 2003 Mazda MPV
The car dies unless you keep you foot on the gas. 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?
They are all related to the same thing your evaporator has a leak or needs changed

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.
