I have a 2004 ES330 later than a hestitation problem. It is good from a full end but next I go with reference to turns on onto highway ramps, afterward I distress the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon following the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery adequately 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 correspondingly far? I ve cleaned the MAF sensor. Checked for links in the intake. taking into account I put my Turbo OBDII app on, all seems fine except that the TPS stays constant around 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 as soon as the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know in the past I link up you? No, I guess that is it.
Its plus worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a sick pump will every result in insufficient fuel instinctive delivered to the engine. Might furthermore be worth cleaning out the idle quickness control motor / valve as these acquire clogged taking place later carbon and some brake cleaner washed through helps clear things off.
Hello the TPS does have an effect on switching the car into idle mode as a result I'd suggest to make positive the throttle plate is 100% closed and not slightly stuck subsequent to carbon. and subsequently get used to the TPS so that the IDL glue is continuous to the E2 pin behind the throttle is closed, and get into circuit in the same way as the throttle is just cracked. Don't make miserable nearly any voltages, the IDL approach is the really important one.
