I have a 2004 ES330 in imitation of a hestitation problem. It is fine from a full end but subsequent to I go roughly speaking turns on onto highway ramps, taking into account I sadden 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 following the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery sufficiently 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 appropriately far? I ve cleaned the MAF sensor. Checked for links in the intake. later than I put my Turbo OBDII app on, all seems good except that the TPS stays constant more or less 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I admit the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know in the past 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 tell you a tiny more practically the misery history. It currently has a master tech qualified idle ventilate rule valve and tps installed. without distressing anything, the last (used) ecu and my original, would run in the car without this symptom.
