unknown why this happens, please help

even when i pull the trigger fully and release fully, the pressure starts to die off, i know its not my tank, could it be the trigger job(kinda sketchy) was like that when i bought the gun off of my friend. im gonna put an intelliframe but could this be the reason why the bolt sticks forward sometime and why the pressure dies off.

Trigger jobs will cause a mess of problems. If you have aftermarket parts, those can be culprits too. Make sure you have all stock on/off components and that your valve is clean and well oiled. Next, make sure the sear isn't excessively worn. The spot that catches the bolt should come to a sharp point. The most important thing is to make sure the trigger rod has a small gap inbetween it and the back of the trigger rod when gassed up. If it's touching the trigger, that's going to cause problems.

Bolt stick you say? Try checking the bolt spring length. The bolt spring should protrude out past the front of the bolt when on the bolt.
