Any idea what might be the cause?
I have a 2010 Toyota camry altise and i am suffering from this hesitation problem at lower speed and i dont have any engine check light. I have shown it to my mechanic and he clean the throttle body but the problem is still there. Service is up to date according to the logbook.
Defective Fuel Pump: The fuel pump pulls the fuel from the gas tank to the engine via the fuel lines. If the pump stops working, malfunctions, or becomes clogged, it will not supply enough fuel to the injectors. This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds.
The 2010 Toyota Camry is a good used midsize car. It has a comfortable ride, respectable power from its base engine, and a strong available V6 engine. It features a spacious cabin and a good amount of storage space.
The often misunderstood check engine light or "service engine soon" message can mean many different things. It could be a misfiring engine, a broken oxygen sensor or simply a loose gas cap. ... In any case, if the check engine light is on in your car, it's time to schedule a service appointment.
Put the key into the ignition and turn on the car but don't turn over the engine. Wait a few minutes then put the fuse back in place. You should notice the check engine light blinking a few times on the instrument panel, then it will go off.
Replacing a faulty oxygen sensor a sensor used to optimize a vehicle's fuel-to-air mixture to increase gas mileage and reduce emissions — is the most common cause for a check engine light.
