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).
The engine âpingsâ or knocks on acceleration. The symptom is more pronounced when the engine is at operating temperature. Engine ping is the result of abnormally high combustion temperatures. The usual cause of engine ping is over advanced ignition timing, an inoperative EGR system or improper fuel usage.
