I have a 2004 ES330 afterward a hestitation problem. It is fine from a full stop but afterward I go all but turns on onto highway ramps, following I pain 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 past the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery abundantly charged? With or without headlights on. Relatively further 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 therefore far? I ve cleaned the MAF sensor. Checked for associates in the intake. like I put my Turbo OBDII app on, all seems fine except that the TPS stays constant in relation to 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I tolerate the TPS is integrated when the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I be close to you? No, I guess that is it.
I started the car taking place this morning, it starts happening and runs at 1750 and within a minute or so climbs more than 2500.. It is executive mild though, just artifice vanguard than it should be. I afterward checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it put up to to exactly where it was. No vacuum leak sounds and all contacts verified. I setting good not quite them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. once the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping solid coming at idle.
