1998 Mazda 626 LX from North America - Comments

I have the same problem with my 94 mazda.

I had the same idling problem with my 1998 Mazda 626 LX. After cleaning the idle air control valve and the mass air flow, nothing changed. I finally brought it to the Mazda dealership and had them run the computer to it for $80.00. Turns out, it was a bad intake gasket. I bought the part for $20.00 and it is about 3 hour job for any mechanic to replace it. When it was replaced, the car runs perfect!
