I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full stop but similar to I go not far off from turns on onto highway ramps, later 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 once the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery abundantly charged? With or without headlights on. Relatively additional 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 thus far? I ve cleaned the MAF sensor. Checked for friends in the intake. subsequent to I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant on the order of 30%. This is a drive-by-wire model fittingly it has not throttle cable or usual TPS. I bow to the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know past 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 say you a tiny more very nearly the misery history. It currently has a master tech recognized idle freshen run valve and tps installed. without moving anything, the last (used) ecu and my original, would govern in the car without this symptom.
in imitation of I begin the car, the engine surges occurring amid 1200 and 2000 rpm assist and forth. I tainted the IAC and the TPS in imitation of no correct in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to accustom yourself the idle zeal screw to demean the rpm and it would hold for a while. Now, the engine is constantly surging to the reduction where I cannot drive it for terrify of damage to the steer train. Any experienced solution?
