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).
Dirty and/or clogged emissions components can also cause a car to stall during acceleration. If filtering components and sensors are not functioning as they should, byproducts from unburned fuel--or low grade fuel--could accumulate, resulting in air not being able to circulate through the system.
