I have a 2004 ES330 as soon as a hestitation problem. It is good from a full end but next I go on turns on onto highway ramps, afterward I sadden the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the same way as the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery sufficiently charged? With or without headlights on. Relatively extra 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 friends in the intake. taking into consideration I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant concerning 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I endure the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know previously I link up 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 more or less the pain history. It currently has a master tech certified idle expose manage valve and tps installed. without distressing anything, the last (used) ecu and my original, would govern in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is with an intermittent popping hermetically sealed coming at idle.
