My Mazda Mx3 Klze turbo is misfiring between 3000 and 4000 rpms. It has a manual fuel gage and I really don't know if it's that. It stays no lower then 45 and no higher then 55. Could that be a problem?

fuel pressure should be 30-37 w/vacuum and 38-46 w/o vacuum hose connected. look for a vacuum leak like a broken hose or one off then have pressure regulator checked. these figures are at idle so higher rpm may be higher.
