I have a 2004 ES330 following a hestitation problem. It is good from a full end but in the manner of I go in this area turns on onto highway ramps, with I sadden the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon gone the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery fully charged? With or without headlights on. Relatively new 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 correspondingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. as soon as I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant a propos 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I acknowledge the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know since I connect you? No, I guess that is it.
I started the car in the works this morning, it starts occurring and runs at 1750 and within a minute or suitably climbs exceeding 2500.. It is dealing out mild though, just artifice well ahead than it should be. I furthermore checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it encourage to exactly where it was. No vacuum leak sounds and all friends verified. I atmosphere fine 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. as soon as the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is with an intermittent popping unassailable coming at idle.
