will do in the am, if the maf did somehow magically go bad from seafoam,going into a vaccum line, it would be a modern miracle, not to mention the ungodly things I will be doing to the seafoam that is left

Did you try putting the original coil pack back in? Bring everything back to the way it was (minus the seafoam and plugs!) and see what happens.
Double check all your wires and connections.

It sounds like you have a vacuum leak. Make sure to check all vacuum connections especially the hose you disconnected. Listen for any hisses that would suggest a vacuum leak. The sea foam should not have damaged anything. One other thing I would check is maybe the PCV valve.

ok, I unplugged the MAF and the car seemed to run no different. Only change was that of course the SES light came on. DIdnt check the code, but I have to assume it is for the maf since it went away soon as I reconnected it. I am at work, and the original coil is at home. I checked my firing order and connections and all seem fine.

The fact that it ran really nice for five minutes may be of help in the diagnosis. What were the conditions when it was running OK? Was the engine cold, or hot? Has it run smoothly again?
