I have a 2004 ES330 similar to a hestitation problem. It is good from a full end but when I go with reference to turns upon onto highway ramps, behind I hurt 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 with the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery abundantly 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 as a result far? I ve cleaned the MAF sensor. Checked for associates in the intake. as soon as I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant in this area 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know 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 little more very nearly the misfortune history. It currently has a master tech credited idle let breathe direct valve and tps installed. without upsetting 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. in the same way as the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping hermetically sealed coming at idle.
