Rossi: Death and taxes - Understanding how 'step-up in basis' works. An IRS building in a file photo. It is often said the only certainties in life are death and taxes. Thanks to estate and inheritance tax, it is not uncommon for them to occur simultaneously.
Probable Causes: An engine that hesitates, stumbles or misfires when accelerating or when it is under load, is an engine that is either sucking too much air, not getting enough fuel, or misfiring. If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS).
A rich diet fed infrequently or a sudden change to rich grass are the most common causes of gassy or spasmodic colic whereas impactions are usually caused by inactive horses on box rest and eating a straw bed. More severe forms of colic, such as a twisted or entrapped piece of intestine, are less predictable. There is not usually a clear cause and they are less likely to be caused by poor management. It was once thought that the act of a horse rolling causes the intestine to twist but that is now known to be wrong.
