I have a 2004 ES330 subsequent to a hestitation problem. It is good from a full end but in imitation of I go in relation to turns on onto highway ramps, in the manner of I upset the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery adequately charged? With or without headlights on. Relatively supplementary 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 consequently far? I ve cleaned the MAF sensor. Checked for contacts in the intake. gone I put my Turbo OBDII app on, all seems fine except that the TPS stays constant all but 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I undertake the TPS is integrated similar to the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know before I be close to 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 approximately the suffering history. It currently has a master tech certified idle freshen direct valve and tps installed. without moving anything, the last (used) ecu and my original, would manage in the car without this symptom.
in imitation of I begin the car, the engine surges in the works with 1200 and 2000 rpm assist and forth. I misused the IAC and the TPS later than no bend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle rapidity screw to lower the rpm and it would withhold for a while. Now, the engine is permanently surging to the point where I cannot steer it for scare of broken to the steer train. Any experienced solution?
