I've had a problem lately with my 04 mazda6 V6. when i start it sometimes it stalls, it will rev up to about 1500 RPM on its own like normal, but then a few seconds later it either completely stalls or the RPM's drop below 500 and it stubbles and then the RPM's go back up. its been doing it more often lately, it used to do it in the fall, but once winter came around it stopped and now its back and it seems to do it more often. I plan on taking it to the dealership anyways, but I was just wondering if any one has had this problem before. It hasnt been to the dealer in a long time anyways, so I am sure its due for a few tech bulletins.

thanks for your help

If I had to guess Id say the Mass Airflow Sensor, but there may be a few TSB's on it...

 

well I ended up taking my car to the dealership, and they replaced the trottle body for the stalling problem. They also replaced the headliner because one of the corners was coming apart, and they replaced the drivers front window regulator becuase it was making a ticking noise when the window would go up or down. after my car being there for a week I finally got it back and I was soo happy, I missed it. then on my way home I got a speeding ticket for 20 over, which really sucked. the cop was actually asking me about me car and how I liked it and stuff like that becuase he needed a bigger car for his family, unfortunantly I wasnt able to get out of the ticket. I guess I was still lucky because he didnt give me a seat belt ticket or reckless driving, becuase in virginia 20 over is reckless. I think I learned my lesson for now that my second ticket in 2 months. I am about to turn 21 and can barely afford the insurance as is, I dont know what I am gonna do when those tickets show up.
