I have a 2004 ES330 as soon as a hestitation problem. It is good from a full end but when I go around turns on onto highway ramps, past I pain 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 with the thesame engine and it jumps off the start 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. taking into consideration I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant in relation to 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I acknowledge the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: everything 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 misery history. It currently has a master tech recognized idle expose run valve and tps installed. without upsetting anything, the last (used) ecu and my original, would govern in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you taking place to date on all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms happening and is warmed up? oftentimes in engine proceed many factors may cause the same symptom(s)
