Before getting it tuned, I had the exact same symptoms everyone else is having here. My idle would drop between 50-150 and it feels like the car is trying to fight to bring it back up. The AFR would also bounce up and down between lean and rich. I do not remember how big of a bounce it was but it was enough for me to see that it is not normal. Now, after the tune, the AFR still bounces but not as drastic as on the base map. The idle is far more consistent and feels normal now. I will need to jump back in my car and really pay attention this time around to see how it is as I haven't really paid much attention to it. Mostly because it hasn't been an issue. Here is a video I made when I was running the base map. It doesn't show it dipping much because I didn't rev it but it does show that it is bouncing about 50 rpm. |
