I have a 2004 ES330 with a hestitation problem. It is fine from a full end but taking into account I go on the order of turns upon onto highway ramps, taking into account I upset the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon once the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery adequately charged? With or without headlights on. Relatively new 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. past I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant roughly 30%. This is a drive-by-wire model correspondingly it has not throttle cable or usual TPS. I allow the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I be close 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 say you a tiny more approximately the hardship history. It currently has a master tech attributed idle air rule valve and tps installed. without moving anything, the last (used) ecu and my original, would direct in the car without this symptom.
