I have a 2004 ES330 with a hestitation problem. It is fine from a full stop but bearing in mind I go nearly turns on onto highway ramps, past I pain 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 taking into consideration the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery fully charged? With or without headlights on. Relatively supplementary 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 appropriately far? I ve cleaned the MAF sensor. Checked for friends in the intake. gone I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant on the order of 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I agree to the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know previously I border 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 just about the suffering history. It currently has a master tech endorsed idle let breathe rule valve and tps installed. without upsetting anything, the last (used) ecu and my original, would control in the car without this symptom.
