2002 Mazda Protege 4 cyl Front Wheel Drive Automatic 270000 miles
I own a 2002 Mazda Protege with 2.0L engine DOHC. My engine check light is on showing a code of P0421-the precat is not achieving threshold temperature to operate properly. It is running to cool. What can be causing such a problem?
have the same problem?
