Question about 2003 Mazda 6
When i accelerate the car makes a very loud squeal sound as i shift through the gears. if was driving ok but a lil rough. now its losing power and will barely go. it pulled codes for mass air flow sensor and two rear o2 sensors... i replaced the idler pulley and belt and still no change. help would b greatly appreciated.
How many miles? V6? Have you had a tune up(spark plugs changed..AT LEAST)? Should be changed about every 60,000 miles, according to the manual. Does your engine burn oil? Check your intake rubber tube, vac lines, pcv tube for crack. Hopefully your catalytic converter isn't the problem due to above...

its the caburtor, it blocks the fuel from the pump and it also bogs out, factory fault you need to replace the caburator and bypass all the smog stuff, just install the o2 sensor into the air intak hose thats what i did

I had the same problem and found that the air admission tube was badly cracked.
Since this let air enter the engine downstream of the mass airflow sensor it is not measured so the engine ECU don't send the proper amount of fuel to provide the right air/fuel mixture. At higher RPM, the vacuum in the tube is enough to close the crack and hide the problem.
I temporarly repaired it with duct tape until I get the part.
