I have a 2004 ES330 like a hestitation problem. It is fine from a full stop but in the manner of I go re turns on onto highway ramps, taking into account I pain the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the same engine and it jumps off the start and has no hesitation.

I don't think the tps has that much control in the substitute of rpm though? I think it deserted adjusts it just about 1k..

Does the engine manage subsequently the MAF disconnected. in the same way as the loud hissing sound this could be your problem. This could be a large vacuum leak ,with the MAF connected it is forlorn measuring the freshen that is getting later than the MAF, thus if the intake manifold is sucking in freshen the freshen to fuel ratio will be definitely out and cause the engine to stal
