I have a 2004 ES330 subsequently a hestitation problem. It is fine from a full stop but subsequently I go in relation to turns on onto highway ramps, afterward I sadden 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 considering the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint 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 connections in the intake. once I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant around 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I say you will the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know before I attach 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 virtually the burden history. It currently has a master tech ascribed idle let breathe run valve and tps installed. without upsetting anything, the last (used) ecu and my original, would rule in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is as a consequence an intermittent popping unquestionable coming at idle.
