Q: Car shuts off while driving. Got fuel pump changed. Throttle position sensor oil pressure switch wires for a tune up done also

Hi there. Usually when a car will stall all of the sudden without warning, it’s caused by a restriction of fuel or an electrical glitch with the ignition system. If you’ve had the throttle position sensor changed, and fuel pump, it’s possible that a different fuel system components is either clogged or damaged with excessive carbon deposits, such as mass air flow sensors or EGR valve. It’s also possible that a dirty fuel filter or air filter, worn out spark plugs or even plug wires are faulty. The best way to have this diagnosed correctly is to have a professional mobile mechanic complete a car starts then stalls inspection at your location.
