I have a 2004 ES330 in the same way as a hestitation problem. It is good from a full end but taking into consideration I go going on for turns on onto highway ramps, similar to I upset the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into consideration the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery abundantly charged? With or without headlights on. Relatively new 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 suitably far? I ve cleaned the MAF sensor. Checked for friends in the intake. bearing in mind I put my Turbo OBDII app on, all seems good except that the TPS stays constant nearly 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I put up with the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know previously 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 tell you a tiny more virtually the trouble history. It currently has a master tech endorsed idle air manage valve and tps installed. without touching anything, the last (used) ecu and my original, would run in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode suitably I'd recommend to create clear the throttle plate is 100% closed and not slightly high and dry with carbon. and subsequently adapt the TPS hence that the IDL fasten is continuous to the E2 glue in the manner of the throttle is closed, and entry circuit taking into consideration the throttle is just cracked. Don't upset more or less any voltages, the IDL open is the in reality important one.
