Hi Galant5Rov,

Firstly, congratulations to you on identifying the Trouble Code. This code relates to the Heated Oxygen Sensor (H02s)

The oxygen sensors supply the computer with a signal that indicates a rich or lean condition during engine operation (i.e. fuel/air metering).

This input information assists the computer in determining the proper air/fuel ratio. A low voltage signal from one or more sensors indicates too much oxygen in the exhaust (lean condition) and, conversely, a high voltage signal indicates too little oxygen in the exhaust (rich condition).

The oxygen sensors are threaded into the exhaust manifold and/or exhaust pipes on all vehicles.

A faulty oxygen sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit can cause the following symptoms.
Related Symptoms

• Surging at idle
• Unstable idle
• Running rough off idle
• Hesitation
• Stumble
• Chuggle
• Poor fuel economy
• Spark knock
• Stalling on acceleration

You must take EXTREME care when removing these sensors, as they can be difficult to remove (seize up). You may require a special tool to remove these without causing damage to the sensor.

Cheers,

What is the firing order for a 2004 mazda 6 v6?

SOURCE: 1999 Mazda 626 antenna won't go down, hums.

Spray the antenna with a spray lubricant (WD40) or similar. and let it sit for an hour.

Then start the car and see what happens.

The antenna is probably full of filth or corrosion..

If that doesn't work take the side cover off the trunk on the side where the antenna is and you will find a plug in electrical connector near the motor that winds the antenna up and down, pull that plug out and the antenna will stop trying to wind itself down..

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.

Might be your traction control has a fault. Is the ABS light also on? If yes, please see my tip at http://www.fixya.com/cars/r6003525-abs_traction_control_lights and let me know if you have questions.
