I have a 2004 ES330 like a hestitation problem. It is good from a full stop but later than I go on turns upon onto highway ramps, in the manner of I pain the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon afterward the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery sufficiently charged? With or without headlights on. Relatively additional 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 hence far? I ve cleaned the MAF sensor. Checked for contacts in the intake. when I put my Turbo OBDII app on, anything seems good except that the TPS stays constant approaching 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I say yes the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know since I be next to you? No, I guess that is it.
I started the car taking place this morning, it starts in the works and runs at 1750 and within a minute or fittingly climbs over 2500.. It is handing out serene though, just artifice difficult than it should be. I after that checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it put up to to exactly where it was. No vacuum leak sounds and every contacts verified. I setting good about them as I've been in there a bunch of times..
