Hello, I checked for hissing sounds but did not hear any. It does not perform very wel I think. When I pres the accelarator it react very slow.

Low idling is usually caused by restriction of the idle air passages and cleaning the throttle body and Idle Air Control valve should help. The hesitation could be due to the low idling speed.

Will cleaning the EGR and Throttle body help?

It should at least get the idle to run correctly. As to hesitation, it might or might not.
