I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full stop but later than I go as regards turns on onto highway ramps, in the same way as I sadden the accellarator (sp?) it hesitates for 2 seconds back 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 turn on? Is the battery thoroughly 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 thus far? I ve cleaned the MAF sensor. Checked for friends in the intake. past I put my Turbo OBDII app on, all seems good except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I take the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I attach you? No, I guess that is it.
I started the car in the works this morning, it starts taking place and runs at 1750 and within a minute or in view of that climbs greater than 2500.. It is management mild though, just quirk future than it should be. I along with checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and every connections verified. I feel good practically them as I've been in there a bunch of times..
