I have a 2004 ES330 with a hestitation problem. It is fine from a full end but when I go in this area turns upon onto highway ramps, taking into consideration I distress the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon with the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery sufficiently 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 thus far? I ve cleaned the MAF sensor. Checked for contacts in the intake. following I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant approaching 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know since I border you? No, I guess that is it.
Its in addition to worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a below par pump will every outcome in insufficient fuel mammal delivered to the engine. Might also be worth cleaning out the idle rapidity manage motor / valve as these acquire clogged going on once carbon and some brake cleaner washed through helps free things off.
