Have you checked for codes? also we should start by doing a compression check to make sure it's mechanically fit.

Hello, are there any warning lights on? Have you checked for codes with a scan tool? Any recent repairs done? How many miles are on the engine?

I haven’t check for compression, the car idle fine, but when you accelerate it won’t rev up to speed when you step on the gas pedal

But the only code a got was for a evap system p0443,p0441
Mazda Mechanic: HDGENE, ASE Certified Technician replied 2 months ago

Ok those codes are only for the evaporative emissions system. They really should cause a lack of power. I would suspect a possible issue with a weak fuel pump or restricted fuel filter. You should check fuel pressure with a fuel gauge, if it drops off when it looses power, it would be a problem with the fuel pump.
