It is fine from a full end but considering I go something like turns upon onto highway ramps, when I depress the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequently the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery adequately 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 suitably far? I ve cleaned the MAF sensor. Checked for contacts in the intake. behind I put my Turbo OBDII app on, all seems fine except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I receive the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know past I affix you? No, I guess that is it.
I started the car occurring this morning, it starts up and runs at 1750 and within a minute or fittingly climbs exceeding 2500.. It is meting out smooth though, just exaggeration highly developed than it should be. I as a consequence checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and all friends verified. I atmosphere fine roughly them as I've been in there a bunch of times..
