Check Engine Light: Codes = 350,353, 354, 355 ??? S70 1999

My check engine light came on yesterday. Stopped by AutoZone to use their free OBDII reader service. Where can I get some info on the codes that were logged? I did not actually see the code reader, but here's what they told me: Code 350,353,354,355 Ignition primary, Ignition secondary

Any help would be great.

    350= Misfire on more than one cylinder, 353 = misfire on cylinder threee, 354 = misfire on cylinder four; 355 = misfire on cylinder five. Plugs are recent or need to be replaced? Intake gasket blown somewhere between three and five? Bad coil packs or wires to coil packs on three, four, and five?

      I replaced the plugs and the Check Engine light reset to off the next day.
      It's back on again. I'm going to work my way to the problem (plugs, then wires/distributor, then coil packs). Where do the wires from the coil packs go (is the distributor tucked under the engine?)?
