Watching a Fiat X19 pull away from you uphill sucks. But the good part was hearing a Honda guy complain about getting beat by a Yaris.

Two more podium finishes, 3rd both days, out of six cars - and lucky to finish at all on Sunday, as the dreaded misfire came back. We believe the car is experiencing fuel starvation, we are generating enough grip and body roll with the slicks that at even 1/2 tank the car will cut under certain conditions. This happened three times during the weekend, and in all the cases the mis went away and car was good after about half a lap. Time to look at getting a fuel cell.

I just saw the video u posted on YT.
-When the misfire appears, does your throttle respond only if u press it lightly?
-Goes away a few seconds later?
-Does you Check engine light blink?

Sorry for asking too much but I'm having a random misfire and the car does the same buzzing sound (not too nice to hear ) when it occurs. And it happens after a long drive (1.5-2 hours) averaging 80-90mph specially when shifting from 3rd to 4th gear
