1998 S70 T5 Misfire at idle, seems to go away on acceleratio

Gentlemen-
This one has me at a loss, as my S70 has a definite miss at an idle and I cannot for the life of me find it. I have replaced my plugs, rotor, and bought a set of IPD blue wires, yet cannot get the raggy, feral miss at an idle stopped, I have even gone so far as cleaning my Idle Valve with chemical cleaner in the hope it was the cause.
This one pisses me off and I have to find it as DEQ is imminent as I need license plates before the end of the Month. ANY Help will be greatly appreciated.

Thanx, S70 fanman

Have you checked compression?

Misfire or stumble at idle that goes away with throttle is often a vacuum leak. I would check all of the hoses carefully.
