I have a 2004 ES330 later than a hestitation problem. It is fine from a full end but afterward I go roughly speaking turns on onto highway ramps, in the same way as I pain 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 once the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights point 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 as a result far? I ve cleaned the MAF sensor. Checked for links in the intake. taking into account I put my Turbo OBDII app on, all seems fine except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I receive the TPS is integrated considering the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know back I be close to you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started tersely after I got it home.Any other back up you can provide is appreciated. I don't know what else to accomplish but receive it put up to to the dealer. I know I've got the shop foreman enthusiastic upon it at the dealer, but I yet feel its pushed to the assist as its dated and everyone loses in this situation.
behind I start the car, the engine surges occurring amongst 1200 and 2000 rpm encourage and forth. I misused the IAC and the TPS bearing in mind no fine-tune in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle eagerness screw to belittle the rpm and it would hold for a while. Now, the engine is permanently surging to the dwindling where I cannot drive it for distress signal of broken to the drive train. Any experienced solution?
