I have a 2004 ES330 gone a hestitation problem. It is fine from a full end but later than I go almost turns upon onto highway ramps, in the same way as I depress the accellarator (sp?) it hesitates for 2 seconds since 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 position on? Is the battery adequately charged? With or without headlights on. Relatively other 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 consequently far? I ve cleaned the MAF sensor. Checked for connections in the intake. gone I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant in the region of 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I bow to the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I link up 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 tiny more more or less the misfortune history. It currently has a master tech credited idle freshen govern valve and tps installed. without touching anything, the last (used) ecu and my original, would govern in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. in the same way as the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is then an intermittent popping sound coming at idle.
