I have a 2004 ES330 past a hestitation problem. It is good from a full end but in the same way as I go all but turns on onto highway ramps, taking into account I hurt the accellarator (sp?) it hesitates for 2 seconds in the past reving up.

Does the engine run behind the MAF disconnected. taking into account the loud hissing solid this could be your problem. This could be a large vacuum leak ,with the MAF linked it is only measuring the freshen that is getting next the MAF, thus if the intake manifold is sucking in air the air to fuel ratio will be completely out and cause the engine to stal
