Hesitation on acceleration in a 2005 Ford Five Hundred could be caused by several issues, including a clogged fuel filter, a failing fuel pump, or dirty fuel injectors, which can restrict fuel flow to the engine. Additionally, problems with the ignition system, such as worn spark plugs or faulty ignition coils, may lead to misfires and poor acceleration. Another potential cause could be a malfunctioning mass airflow sensor or throttle position sensor, affecting the engine's air-fuel mixture. Regular maintenance and diagnostic checks can help identify and resolve these issues.
There are many things that could cause hesitation on acceleration in a vehicle. It could be the fuel pump, the gas pump, fuel pump relay, or an electrical problem.
Could be timing belt/chain is worn
Hesitation upon acceleration in a Taurus could be caused by a variety of issues, such as a clogged fuel filter, a dirty air filter, a malfunctioning mass airflow sensor, or a problem with the fuel injectors or spark plugs.

Intermittent hesitation in a car could be caused by many things. The fuel filter, the EFI, and spark plugs might be the cause. A loose wire can also cause this. Newer cars have many plugs and connectors that could have come loose.
Start by checking the EGR system.
Possibly, yes. If the injection system is not providing a steady and regular supply of fuel to the engine, shuddering and hesitation could result. Note that the fuel pump is part of the fuel system, and can cause similar symptoms if it's failing.
There are many things that can cause a 2000 Blazer to have hesitation problems. Some causes could be bad plugs and wires, fuel filter, or the EGR valve.
Could be, time for a tune up.
Several factors can cause hesitation when accelerating, such as a clogged fuel filter, dirty fuel injectors, faulty spark plugs, or a failing mass airflow sensor. It's also possible that issues with the transmission, such as a slipping clutch or low transmission fluid, could be contributing to the hesitation. A diagnostic check by a mechanic can help pinpoint the exact cause of the problem.
