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).
Question type: Maintenance & Repair. When I step on the gas my car is very sluggish to respond. It does not misfire or anythign like that. The engine reves up like normal but I get sluggish acceleration. I have had this happen before and when I get an oil change it has gotten better. It has not helped this time.
