I have a 03' Mazda6. Im expierencing some idling problems. I took it to a mechanich shop, told me it was a cylinder misfire & that I needed a fuel injecion clean out & a complete tune up. Did that, still didnt fix my problem. I admitt though its not asbad as before. But now Ive noticed when my A/C is on pfull blast & I turn it off, my car dies on me, or I could just be at a stoplight & my car will idle then die. Has anyone had the same problem Ive had? Or can someone tell me whats going on?

 

Is the 6 a 4 cylinder or V6? manual trans or automatic? Could well have a vacuum leak or idle control valve that is sticking. Is the stalling and low idle occuring all of the time now or just once and a while.
