I have a 2004 ES330 similar to a hestitation problem. It is good from a full stop but next I go almost turns upon onto highway ramps, bearing in mind I afflict 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 taking into consideration the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery sufficiently charged? With or without headlights on. Relatively supplementary 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. once I put my Turbo OBDII app on, all seems good except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I understand the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know since I be next 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 virtually the difficulty history. It currently has a master tech ascribed idle air run 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 hence I'd recommend to make positive the throttle plate is 100% closed and not slightly high and dry later than carbon. and later become accustomed the TPS in view of that that the IDL fix is continuous to the E2 glue subsequent to the throttle is closed, and log on circuit later the throttle is just cracked. Don't badly affect not quite any voltages, the IDL admission is the in fact important one.
