Default Hesitation with lite/ medium throttle application

I am new so bare with me. I have A 99 Jetta VR 6. I have developed a hesitation while applying lite to medium throttle application, but when I push a little harder in the throttle the car takes off like a rocket... I am stumped, not sure what would causes this, maybe vaccume ?
Also when the car warms up its not as violent, and this also triggers my EPC and I lose acceleration .Can I get so advice please and thank you

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing.

Who won't scan you car? Aftermarket stereo's do give faults code.

They say that if the stereo is installed wrong it will fry there computer,
But I did take the air box and intake apart today and cleaned it up. That corrected the issue and my car is back to 100% running condition
