Tom, when did you pull the screen? Plus, you were just working around the air bridge. As mentioned above, check carefully for air leaks in the intake area.

A lean condition can be caused by unmetered air making it past the MAF - in other words, a leak. Go over the intake system from the air filter back and double ceck every connection carefully to rule that out first.
