Oh driver side plug by the firewall.. my must you be in such a tight place?! If I could get that bar out of the way it might not be so bad.
What # plug is the middle passenger side? #2? It had unburnt fuel on it, and I believe the code was for plug #2 misfire.
(Update: I got 'er done shortly after posting this^. Running like a champ now. I managed to fit the 4Runner all the way in the garage which was good considering it was snowing right after I started working on it. I wish I had some throttle body cleaner on hand.. it was extremely dirty. I also have a good deal of slack in my throttle/cruise/trans kickdown cables.. I may sneak out and take care of that tomorrow.)
