I need help! I have a 2006 Mazda Tribute. 6 cylinder. 3.0 L engine. Everything mechanical in my car has been replaced. New engine. New water pump. New radiator. New O2 sensors. New thermostat.
All 3 catalytic converters are new.... the car
will start...will run with no issues.
However..one of the catalytic converters is
still overheating and turning cherry red.
Everything is brand new....WHAT IS
WRONG? :(
