I've had the same problems, though my irons are longer than you, my driver is 210-230. A lot of reasons, without video, no way to tell, but i'll give you something i've been told cause i am having the same struggles
keeping weight on the right side (right handed) causing deloft in the club at impact
-- shifting weight to left side and rotating arms to have logo of left hand glove point to target to deloft the club
My ball striking has gotten really decent, but i just started working on this at the range yesterday.
regular backswing, driver the hips and rotate the hips hard and keep the arms relax and passive. It's almost like i'm rotating with my hips and letting my arms go where they may, I have to say i hit my 8iron carry about 5-6 yards further, albiet, not consistent at all!
hope that helps.
