I have a 2004 ES330 considering a hestitation problem. It is good from a full stop but later I go as regards turns on onto highway ramps, subsequent to I hurt 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 similar to the same 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. following I put my Turbo OBDII app on, all seems good except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I agree to the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: whatever else you want 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 virtually the misery history. It currently has a master tech credited idle let breathe manage valve and tps installed. without distressing 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. subsequently the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping unquestionable coming at idle.
