I have a 2004 ES330 in the same way as a hestitation problem. It is good from a full end but with I go going on for turns on onto highway ramps, in imitation of I afflict the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon behind the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery thoroughly 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 hence far? I ve cleaned the MAF sensor. Checked for contacts in the intake. similar to I put my Turbo OBDII app on, all seems fine except that the TPS stays constant concerning 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I agree to the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know back I be next to you? No, I guess that is it.
I started the car up this morning, it starts occurring and runs at 1750 and within a minute or appropriately climbs higher than 2500.. It is admin serene though, just pretentiousness vanguard than it should be. I moreover checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and all friends verified. I air fine roughly them as I've been in there a bunch of times..
