I have a 2004 ES330 behind a hestitation problem. It is fine from a full end but when I go in this area turns upon onto highway ramps, like I sadden the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon later than the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery fully 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. similar to I put my Turbo OBDII app on, all seems fine except that the TPS stays constant approaching 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I tolerate the TPS is integrated as soon as the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know back I border 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 nearly the trouble history. It currently has a master tech certified idle freshen manage valve and tps installed. without moving anything, the last (used) ecu and my original, would rule in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode consequently I'd suggest to make clear the throttle plate is 100% closed and not slightly grounded as soon as carbon. and subsequently adjust the TPS so that the IDL pin is continuous to the E2 glue behind the throttle is closed, and retrieve circuit afterward the throttle is just cracked. Don't distress roughly any voltages, the IDL gate is the in fact important one.
