Thanks, I will exhaust all the other suggestions made here first before going the "dealership" route, ouch!

Speaking of MAF sensor....When I was pulling the air intake "box lid" off I lifted too much and broke one of the tabs that holds it down. Could it be "sucking" air without going through the filter first and causing additional problems, or is that a stretch (I'm sure you can tell I'm grasping at straws at this point).
