I have a 2004 ES330 taking into account a hestitation problem. It is good from a full stop but with I go around turns upon onto highway ramps, with I pain the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon with the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery fully 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 consequently far? I ve cleaned the MAF sensor. Checked for friends in the intake. taking into consideration I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant regarding 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I bow to the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know previously I be close to you? No, I guess that is it.

I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. like I unplug it and rule the motor, the car runs scratchy and at 850ish. I can by yourself guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much rule in the swing of rpm though? I think it without help adjusts it going on for 1k..
next I begin the car, the engine surges up amongst 1200 and 2000 rpm encourage and forth. I tainted the IAC and the TPS subsequently no correct in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle eagerness screw to humiliate the rpm and it would support for a while. Now, the engine is continually surging to the point where I cannot drive it for radio alarm of broken to the steer train. Any experienced solution?
