I have a 2004 ES330 past a hestitation problem. It is fine from a full stop but behind I go on the order of turns upon onto highway ramps, past I upset 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 in the same way as the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery abundantly charged? With or without headlights on. Relatively further 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 connections in the intake. later I put my Turbo OBDII app on, everything seems good except that the TPS stays constant concerning 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I assume the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know past I be close to you? No, I guess that is it.

Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a little more roughly the difficulty history. It currently has a master tech endorsed idle ventilate control valve and tps installed. without touching anything, the last (used) ecu and my original, would control in the car without this symptom.
in the manner of I begin the car, the engine surges in the works in the midst of 1200 and 2000 rpm support and forth. I misused the IAC and the TPS taking into account no fiddle with in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to get used to the idle eagerness screw to belittle the rpm and it would hold for a while. Now, the engine is for eternity surging to the reduction where I cannot drive it for radio alarm of damage to the drive train. Any experienced solution?
