2006 Honda Civic Hybrid isn't accelerating properly

My 2006 Honda Civic Hybrid does not accelerate properly recently. I push the gas pedal, but no acceleration, especially on the hill. In the parking mode, there is no problem for start and engine work, even in -40 deg centigrade.

Have you had the engine serviced lately? New air filter, new fuel filter, spark plugs, etc.?

It’s a hybrid, so you need to have the gas engine checked as well as the electric motor and battery.

No check engine or IMA light on?
