I have a 2004 ES330 similar to a hestitation problem. It is fine from a full stop but considering I go with reference to turns upon onto highway ramps, similar to I pain the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequent to 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 further 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 fittingly far? I ve cleaned the MAF sensor. Checked for connections in the intake. behind I put my Turbo OBDII app on, all seems fine except that the TPS stays constant nearly 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I take the TPS is integrated when the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know previously 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 more or less the burden history. It currently has a master tech recognized idle air manage valve and tps installed. without moving anything, the last (used) ecu and my original, would direct in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is as well as an intermittent popping unquestionable coming at idle.
