Mazda Millenia S High Idle Cold Start
My Mazda Millenia S (EUNOS 800M here in Australia) is idling at over 2000 RPM during cold start. Once she reaches full operating temp idle returns to normal.
Mazda can't identify the fault and I've spent a bunch seeking resolution. The vehicle is in amazing condition having only covered 86,000 miles / 141,000 kms and remains faultless with the exception of this bug which is driving me nuts.
Can anyone out there offer an avenue of investigation?
