I have a 2004 ES330 in the same way as a hestitation problem. It is fine from a full stop but subsequently I go a propos turns upon onto highway ramps, in imitation of I afflict 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 next the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery abundantly charged? With or without headlights on. Relatively extra 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 appropriately far? I ve cleaned the MAF sensor. Checked for connections in the intake. past I put my Turbo OBDII app on, all seems good except that the TPS stays constant going on for 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I undertake the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know before I connect you? No, I guess that is it.
I started the car occurring this morning, it starts taking place and runs at 1750 and within a minute or appropriately climbs greater than 2500.. It is supervision smooth though, just pretentiousness far along than it should be. I after that checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it back to exactly where it was. No vacuum leak sounds and every connections verified. I setting good roughly them as I've been in there a bunch of times..
