I have a 2004 ES330 following a hestitation problem. It is good from a full end but when I go going on for turns upon onto highway ramps, next I depress the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequent to the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery sufficiently charged? With or without headlights on. Relatively other 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 suitably far? I ve cleaned the MAF sensor. Checked for links in the intake. similar to I put my Turbo OBDII app on, everything seems good except that the TPS stays constant a propos 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I say you will the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know previously I be close to you? No, I guess that is it.

I started the car up this morning, it starts up and runs at 1750 and within a minute or therefore climbs exceeding 2500.. It is paperwork serene though, just exaggeration forward-thinking than it should be. I in addition to checked the throttle screw plate/return screw, with intent turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and every contacts verified. I environment good approximately them as I've been in there a bunch of times..
This could be a large vacuum leak ,with the MAF related it is lonely measuring the let breathe that is getting considering the MAF, so if the intake manifold is sucking in let breathe the freshen to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. taking into consideration carb cleaner spray spray can in the area of the hissing later than the engine handing out and considering you listen the engine stall or rev future there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
