I have a 2004 ES330 like a hestitation problem. It is good from a full stop but with I go in relation to turns upon onto highway ramps, in the same way as I pain the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon next the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery sufficiently charged? With or without headlights on. Relatively other 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. similar to I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant a propos 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I consent the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know since I connect 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 roughly the misery history. It currently has a master tech attributed idle expose control valve and tps installed. without moving anything, the last (used) ecu and my original, would control in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is after that an intermittent popping unassailable coming at idle.
