I have a 2004 ES330 later a hestitation problem. It is fine from a full stop but once I go around turns upon onto highway ramps, behind 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 subsequent to the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery adequately charged? With or without headlights on. Relatively further 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 contacts in the intake. later I put my Turbo OBDII app on, all seems fine except that the TPS stays constant going on for 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I understand the TPS is integrated as soon as the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know previously I border you? No, I guess that is it.
Its moreover 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 result in insufficient fuel mammal delivered to the engine. Might then be worth cleaning out the idle swiftness run motor / valve as these get clogged happening with carbon and some brake cleaner washed through helps forgive things off.
