I've found at least two threads on this via search and I'm sure there are a handful of others somewhere, but after reading the most recent ones it appears that there is no real solution to this problem...here is one thread about it (or at least part of this thread)- http://forum.mazda6club.com/index.php?show...&hl=stutter
Has anyone found a solution for this yet? Or, what exactly causes this? I experience a stutter/rough acceleration pretty often now. Before it's asked, I've had nothing but 93 octane from three different gas stations (BP, Shell, Marathon). I'm pretty close to taking it to the dealer because it seems to be getting worse, moving from annoying to a real problem. I noticed it a handful of times before I went and had the reflash done, but it wasn't anywhere near the point it is now so I'm not sure if I should suspicion the reflash or something else. I drove the car for about four days without noticing it after the reflash.
I've tried to rule out variables like wind, gas brand, roads (there are a lot of uneven ones around here), and temperature and can say that I don't think any of them are a factor. I'm wondering if it could be an air/fuel ratio issue with the ECU?
