I have a 2004 ES330 bearing in mind a hestitation problem. It is fine from a full stop but subsequent to I go around turns upon onto highway ramps, considering I distress the accellarator (sp?) it hesitates for 2 seconds previously reving up.

This could be a large vacuum leak ,with the MAF partnered it is unaided measuring the freshen that is getting in imitation of the MAF, thus if the intake manifold is sucking in expose the ventilate to fuel ratio will be definitely out and cause the engine to stal
