I accelerate a little more noice stops. If I let

May be the valves or rocker arms out of adjustment.

Would it make that noise if bad timing belt or timing belt tensioner?

Its possible need to look it over real good see if you can replicate it while someone listens with hood up, if it does it in park/neutral and giving it gas.

Yes it will do it in neutral aswell
