2005 Mazda 3 4 cyl Two Wheel Drive Automatic 65000 miles
I'll try and keep this short but clear. I have the 2.0 version of this car. I changed out both O2 sensors and I'm still having problems with a rough start loud idle and if the fan is on it acts like it wants to stall out sometimes. After an oil change the thing runs likie new but a week later, give or take some days, it's back to its old tricks. Teh air filter is clean and none of the hoses look bad. The main symptoms are the loud engine noise, which is almost constant, the rough idle when it comes to a stop or the foot is taken off of the gas, especially when the a/c or heater fan is on. Any help would be greatly appreciated.
