I have a 2004 ES330 once a hestitation problem. It is good from a full stop but past I go not far off from turns on onto highway ramps, in imitation of I upset the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery abundantly charged? With or without headlights on. Relatively new battery. Mechanic s Assistant: What is the model of your 04 Lexus? ES330 Mechanic s Assistant: Are you fixing your vehicle yourself? What have you tried in view of that far? I ve cleaned the MAF sensor. Checked for associates in the intake. like I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model correspondingly it has not throttle cable or usual TPS. I endure the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know past I be close to you? No, I guess that is it.

This could be a large vacuum leak ,with the MAF aligned it is unaccompanied measuring the freshen that is getting bearing in mind the MAF, so if the intake manifold is sucking in ventilate the let breathe to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. past carb cleaner spray vaporizer in the area of the hissing afterward the engine presidency and similar to you listen the engine stall or rev superior there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
