I have a 2004 ES330 considering a hestitation problem. It is good from a full stop but when I go vis--vis turns upon onto highway ramps, subsequent to I depress the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the manner of the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery thoroughly 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. later than I put my Turbo OBDII app on, all seems fine except that the TPS stays constant in the region of 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I acknowledge the TPS is integrated once 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 tell you a little more more or less the hardship history. It currently has a master tech ascribed idle freshen run valve and tps installed. without distressing anything, the last (used) ecu and my original, would manage in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. subsequent to the MAF is plugged in next the car will stall unless I put my foot on the accelerator. There is along with an intermittent popping hermetic coming at idle.
