Accelaration issues.

#1
Please help.
I have a 2010 1.8l corolla. Recently it is accelerating slowly. It does rev but the acceleration is very slow.
We scanned but it did not give any code. However, the check engine light flashes all the time.
Does anyone know what could wrong?

did you check spark plugs? clean mass air flow sensor? clean throttle body? Injectors may need to be cleaned. I would start with these simple steps first.

We did all that unfortunately that did not do anything. What is weird is that there is not code when the mechanic scan it.
