I have a 2004 ES330 in the same way as a hestitation problem. It is fine from a full stop but once I go approaching turns on onto highway ramps, bearing in mind I upset 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 later the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery adequately 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 associates in the intake. afterward I put my Turbo OBDII app on, all seems fine except that the TPS stays constant something like 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I undertake the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know previously 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 say you a little more more or less the problem history. It currently has a master tech official idle ventilate run valve and tps installed. without upsetting anything, the last (used) ecu and my original, would run in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode thus I'd recommend to create definite the throttle plate is 100% closed and not slightly beached similar to carbon. and later accustom yourself the TPS appropriately that the IDL glue is continuous to the E2 pin considering the throttle is closed, and retrieve circuit once the throttle is just cracked. Don't distress not quite any voltages, the IDL right of entry is the in point of fact important one.
