Well, when I got it all back together the car wouldn't run at all... I was out of time to work on it, so that's where it sat until yesterday.
I pulled the plenum again to recheck everything and discovered that I had two of the ignition coils swapped on the drivers side of the car. When I pulled the plenum the last time to check the connector for the ignition module, I also pulled the ignition coils and the plate above the starter out to retrieve a dropped bolt and must have got them mixed up then.
I got it all back together and double checked my vacuum line going to the map sensor....fired right up and didn't throw a code! Thanks for your help, guys!

jon_d4,
I just got through doing my first plenum pull and encountered the same problem you described...it starts and runs, but really rough, almost like a few cylinders are missing.
I noticed early on you mentioned checking the MAP vacuum line initially and it still wouldn't start. But, on your last plenum pull you thought it was the MAP vacuum line. Was there something you noticed the last time around that led you to believe it was the MAP vacuum line? Too loose? Did you have to fix the seals as some have done with crazy glue?
I inspected my MAP vacuum line twice and it seemed alright...although I can't say for sure that it somehow isn't leaking despite my visual inspection.
Just trying to get a feel for what your problem was before I pull the plenum again. By the way, I changed my plugs, wires, coils and injectors, so I have a lot of investigating to do...
It ran fine (other than a slight miss I figured had to do with the injectors; original with only 7K miles on the car) before I pulled the plenum.
