Are you SURE it not overpressurized? MQs wil vent over about 300 psi. Try turning your reg down to OFF and go up.

If I go under it gets worse

Are you sure you have the poppet spring installed?

Try checking out the poppet face seal. Is the screw snug? Try flipping it. If no joy, maybe you imght have to warranty it and get a new face seal.

yes everything is as it should be but one weird thing is when I jiggle the wires a little it will either get worse or better.I had sealed once but I started trying it out and the leak returned

jiggling the wires should do nothing unless the valve is perhaps not seated properly, or you are getting a pilot leak rather than a barrel leak.

here's a question ... how tight is the poppet in the bore?

by the way, did you re-fill your tank/ 300-400 psi out of the tank is not enough to operate he mQ reliably.

I took it apart and saw the spring was out of alignment so I did my best to align it and now I get this baby leak that dosent really bother me but later through the day it got louder. Should the MQ2 not be completely leak free?

Spring was out of alignment? What do you mean by that?

That's not really possible unless you kink it and tighten it, which would damage the spring. I wonder if that's what happened?

Well not dead center basically.
