Okay guys I need help. I have a 2003 Mazda 6 with a V6. The car runs fine before it reaches normal operating temperature then the car does one of two things it either stalls out completely, or does not respond at all to the gas pedal, with the idle dropping to between 1200 and 1500 rpm pulsing between the two. At this point I have to switch the ignition off and restart the car this seems to reset the idle and allows the car to travel a little further but it will stall over and over. When the temperatures are cooler outside it runs fine longer, but as soon as the car warms up it will start to stall, especially if I run the air conditioner as this raises the temperature sooner. Does anyone have a clue what this might be, the dealer wants to just start switching out parts, I dont want to go broke, lol. The check engine light is on, and the code came up as bank 1 o2 sensor, and multiple misfires.
