Engine stumble after rev limiter
Hey guys, wanted to know what you think may be the issue that is cropping up here.
I was at the autocross today and there were several areas where it wasn't worth the time to shift up to 3rd so I left it in 2nd gear and rode the rev limiter for a moment.
The two time I did this, when I got back on the throttle to accelerate out of the corner, the engine would stumble - almost like I only have 3 cylinders, and power was very low. It would do this for a short second, maybe two seconds, and then smooth out and go back to normal.
I have video of it, you can hear the stumbe when I get back on the gas at 0:17 and 0:40.
My thoughts are that my red line cut out is on the wrong setting and so when i'm bouncing off the rev limiter I'm maybe flooding the cylinder with gas, but I don't really know.
