I have a 2004 ES330 considering a hestitation problem. It is good from a full end but next I go with reference to turns on onto highway ramps, gone I depress 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 past the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery sufficiently 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. when I put my Turbo OBDII app on, all seems good except that the TPS stays constant going on for 30%. This is a drive-by-wire model as a result it has not throttle cable or normal TPS. I believe the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I link up you? No, I guess that is it.
Its next 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 all upshot in insufficient fuel living thing delivered to the engine. Might afterward be worth cleaning out the idle speed govern motor / valve as these acquire clogged taking place past carbon and some brake cleaner washed through helps clear things off.
