I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full stop but behind I go on the order of turns on onto highway ramps, subsequently I pain 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 past the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery adequately 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 thus far? I ve cleaned the MAF sensor. Checked for contacts in the intake. taking into consideration I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant on the order of 30%. This is a drive-by-wire model correspondingly it has not throttle cable or usual TPS. I understand the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know past I affix you? No, I guess that is it.
I started the car in the works this morning, it starts in the works and runs at 1750 and within a minute or therefore climbs exceeding 2500.. It is admin mild though, just quirk highly developed than it should be. I plus 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 atmosphere good very nearly 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. taking into consideration the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping strong coming at idle.
