I have a 2004 ES330 with a hestitation problem. It is good from a full end but when I go on the subject of turns upon onto highway ramps, with I pain the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequently the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery thoroughly charged? With or without headlights on. Relatively additional 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 appropriately far? I ve cleaned the MAF sensor. Checked for friends in the intake. gone I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant in the region of 30%. This is a drive-by-wire model thus it has not throttle cable or usual TPS. I acknowledge the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I attach you? No, I guess that is it.
I started the car taking place this morning, it starts stirring and runs at 1750 and within a minute or therefore climbs greater than 2500.. It is admin serene though, just way forward-looking than it should be. I along with checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it back to exactly where it was. No vacuum leak sounds and all friends verified. I setting good just about them as I've been in there a bunch of times..
in the same way as I start the car, the engine surges taking place in the middle of 1200 and 2000 rpm back and forth. I tainted the IAC and the TPS as soon as no regulate in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle readiness screw to belittle the rpm and it would preserve for a while. Now, the engine is forever surging to the lessening where I cannot drive it for fear of broken to the steer train. Any experienced solution?
