one thing I could think to try would be to use a variable to "save" the value and a counter.

If the value = 127 three times in a row, disable movement until some "non-127" value.

Pseudo code might look a little like this......

if (fwd == 127) or (rev == 127)
{
count++;
}else
{
count = 0;
disable = false;
}

if (count == 3)
{
disable = true;
}

Hope this helps you.
