its actually pretty easy if you remove the glove box, which is only a couple of bolts pull it out that will then allow you to take out the large piece of plastic down by the passengers left knee area! then you can easily reach the t.b. and all the sensors are a snap, cuz you have opened up such a large workspace..........I wanted to take off the intake plenum to check out if there are any restrictions myself, but it looks like a pita! It's gotta take hours and hours to take it all apart and put it back together again. Take some pictures of everything, please.
