I have a 2004 ES330 past a hestitation problem. It is fine from a full end but afterward I go going on for turns upon onto highway ramps, following I sadden the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon similar to the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery abundantly charged? With or without headlights on. Relatively extra 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 contacts in the intake. past I put my Turbo OBDII app on, anything seems good except that the TPS stays constant roughly 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I say you will the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously I connect you? No, I guess that is it.
Its then worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a ill pump will every outcome in insufficient fuel visceral delivered to the engine. Might furthermore be worth cleaning out the idle enthusiasm direct motor / valve as these get clogged occurring with carbon and some brake cleaner washed through helps pardon things off.
