    Hello, my prius 2010 (III) accelerate much slower than before. I started noticing this after I picking up my car from the airport. Parked the car there for a week. I have the dealer checked the computer but no error codes found. My car has almost 250k KM on it. I have not replaced the spark plugs the last three years. Could it be the spark plugs?

    Your car is 5 years old, not 3 years old. Ever replaced the spark plugs before?

    If the spark plugs are original, then I suggest you replace them. You should also clean the throttle body and MAF sensor while you're at it.

    Your acceleration issue might be related to low battery SOC and possibly dirty air filters.

    Maybe plugs were replaced 3 years back?

    In europe, spark plugs are every 90.000 km.
