You found Bay 13 which is a good site. To inspect it, it's easier to just remove the air intake hose from the air cleaner to the throttle body to get it out of the way. You can then look in the flame trap opening with a small mirror and strong light to see if it is really cruddy. It will be to the firewall side of the elbow if I remember correctly and you need to turn it about 1/8 turn clockwise as you face the firewall to release it from it's mounting hole. Once out ( it's connected to two hoses that you don't want to dislodge as they go under the intake manifold) you can clean it with FI cleaner if it isn't bad or replace it. They can be a royal pain to remove from the holder to the tune of drilling a small hole in it and screwing in a screw which gives you something to pull on..
