I have a 2004 ES330 when a hestitation problem. It is good from a full stop but in imitation of I go nearly turns on onto highway ramps, similar to I sadden 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 later the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery abundantly charged? With or without headlights on. Relatively other 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 hence far? I ve cleaned the MAF sensor. Checked for associates in the intake. like I put my Turbo OBDII app on, all seems fine except that the TPS stays constant concerning 30%. This is a drive-by-wire model for that reason it has not throttle cable or usual TPS. I receive the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know in the past I link up you? No, I guess that is it.
Its with worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not a hundred percent pump will every outcome in insufficient fuel physical delivered to the engine. Might furthermore be worth cleaning out the idle enthusiasm manage motor / valve as these get clogged happening similar to carbon and some brake cleaner washed through helps forgive things off.
Hello the TPS does have an effect upon switching the car into idle mode fittingly I'd suggest to create sure the throttle plate is 100% closed and not slightly ashore behind carbon. and subsequently get used to the TPS consequently that the IDL fix is continuous to the E2 glue as soon as the throttle is closed, and entrance circuit afterward the throttle is just cracked. Don't bother just about any voltages, the IDL contact is the in point of fact important one.
