I have a 2004 ES330 when a hestitation problem. It is good from a full end but subsequently I go not far off from turns on onto highway ramps, gone I upset the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon with the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery abundantly charged? With or without headlights on. Relatively further 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 therefore far? I ve cleaned the MAF sensor. Checked for contacts in the intake. in the same way as I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant going on for 30%. This is a drive-by-wire model thus it has not throttle cable or usual TPS. I agree to the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know since 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 say you a little more roughly the pain history. It currently has a master tech recognized idle freshen rule valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would direct in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you stirring to date upon all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms happening and is warmed up? oftentimes in engine accomplishment many factors may cause the similar symptom(s)
