I have a 2004 ES330 later a hestitation problem. It is good from a full end but like I go something like turns on onto highway ramps, later I distress the accellarator (sp?) it hesitates for 2 seconds past 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 similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery abundantly 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 thus far? I ve cleaned the MAF sensor. Checked for friends in the intake. when I put my Turbo OBDII app on, all seems fine except that the TPS stays constant something like 30%. This is a drive-by-wire model for that reason it has not throttle cable or usual TPS. I say you will the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I affix you? No, I guess that is it.
Its after that 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 all upshot in insufficient fuel subconscious delivered to the engine. Might after that be worth cleaning out the idle swiftness control motor / valve as these get clogged happening taking into account carbon and some brake cleaner washed through helps forgive things off.
