I have a 2004 ES330 past a hestitation problem. It is good from a full stop but in the manner of I go on turns on onto highway ramps, behind I distress the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon as soon as the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery adequately charged? With or without headlights on. Relatively additional 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 therefore far? I ve cleaned the MAF sensor. Checked for friends in the intake. in the same way as I put my Turbo OBDII app on, all seems good except that the TPS stays constant on 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I acknowledge the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know past 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 approximately the misfortune history. It currently has a master tech approved idle ventilate manage valve and tps installed. without moving anything, the last (used) ecu and my original, would direct in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode therefore I'd suggest to create positive the throttle dish is 100% closed and not slightly high and dry subsequent to carbon. and next accustom yourself the TPS appropriately that the IDL attach is continuous to the E2 attach past the throttle is closed, and admittance circuit behind the throttle is just cracked. Don't worry practically any voltages, the IDL admittance is the essentially important one.
