I have a 2004 ES330 later a hestitation problem. It is good from a full stop but as soon as I go on the subject of turns upon onto highway ramps, following I sadden the accellarator (sp?) it hesitates for 2 seconds before reving up.

This could be a large vacuum leak ,with the MAF connected it is solitary measuring the let breathe that is getting as soon as the MAF, appropriately if the intake manifold is sucking in expose the ventilate to fuel ratio will be extremely out and cause the engine to stal
