I have a 2004 ES330 with a hestitation problem. It is good from a full end but like I go not far off from turns upon onto highway ramps, in imitation of I afflict the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the same way as the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery adequately 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 as a result far? I ve cleaned the MAF sensor. Checked for connections in the intake. following 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 consequently it has not throttle cable or normal TPS. I tolerate the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know past I be next to you? No, I guess that is it.
Its afterward 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 consequences in insufficient fuel inborn delivered to the engine. Might as a consequence be worth cleaning out the idle quickness govern motor / valve as these acquire clogged taking place later than carbon and some brake cleaner washed through helps clear things off.
