Hi, I would start by checking your throttles connections, unplug it and check the pins. People do have trouble with Himiway twist throttles, if this is the case, they should send you a new one. It seems owners have problems with intermittent hall sensors. One other thing to check is that your brake sensor cut offs are not getting hung up anywhere. If they start jumping in and out it can make acceleration very erratic. Throttles are not too expensive, if need be, you can check your pin out type and buy a different brand to see if that fixes the problem. Good luck.
