No codes at all. That's what is confusing me. Now, I haven't stayed in it to long once it started doing it. But I did make it repeat the symptoms about 4 times in a row for about 2 seconds each time before I let out of it. It doesn't matter if it downshifts WOT or going from a stop WOT. Once I get to about 3k RPMs it bucks like it's cutting all power off and on.
