misfire all cylinders >>>>> HELP! 850

Hi all,

I have a 96 850 turbo 103k. I am trying to diagnose a misfire all cylinders. I have replaced all of the common tune up parts.

plugs (volvo - proper gap)
Wires (bogicord)
Cap and Rotor (bosch)
ignition coil Karlyn

New air filter

The only codes that I am getting is for misfire cylinder 1 through 5 and random misfire.

The car idles good. It does not sound like I have a vac leak anywhere.

BTW, The misfire is intermittent. SO, I don't believe it to be a timing issue. And since it is all cylinders I am thinking that it is unlikely to be a compression issue. (all assumptions).

Can anyone point me in a direction????
