but my guess is that maybe a pin on the ignition module got bent trying to get that long connector on the back plugged in. Take off the map sensor bracket and get your 1/4" socket out...

So, after checking the MAP sensor vacuum, I pulled the plenum a third time to check the connector for the ignition module. I was having trouble getting to it without lifting the plenum up. All the pins on the connector look good. On the bright side, I'm getting a lot faster at removing/reinstalling the plenum....
