I have a 2004 ES330 subsequently a hestitation problem. It is good from a full end but afterward I go a propos turns upon onto highway ramps, behind I upset 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 in the manner of the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery abundantly 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 in view of that far? I ve cleaned the MAF sensor. Checked for links in the intake. subsequently I put my Turbo OBDII app on, all seems good except that the TPS stays constant in the region of 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I undertake the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I affix 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 little more practically the pain history. It currently has a master tech official idle ventilate run valve and tps installed. without disturbing 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. next the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping hermetically sealed coming at idle.
