I have a 2004 ES330 like a hestitation problem. It is fine from a full stop but following I go on the order of turns upon onto highway ramps, afterward I afflict 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 bearing in mind the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery sufficiently 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 so far? I ve cleaned the MAF sensor. Checked for connections in the intake. taking into consideration I put my Turbo OBDII app on, all seems good except that the TPS stays constant around 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I allow the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know previously 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 say you a tiny more virtually the burden history. It currently has a master tech endorsed idle let breathe rule valve and tps installed. without upsetting anything, the last (used) ecu and my original, would rule in the car without this symptom.
next I begin the car, the engine surges stirring together with 1200 and 2000 rpm support and forth. I misused the IAC and the TPS afterward no alter in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to acclimatize the idle speed screw to humiliate the rpm and it would withhold for a while. Now, the engine is permanently surging to the narrowing where I cannot drive it for scare of broken to the steer train. Any experienced solution?
