I have a 2004 ES330 similar to a hestitation problem. It is good from a full stop but later than I go around turns upon onto highway ramps, next 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 gone the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint 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 therefore far? I ve cleaned the MAF sensor. Checked for friends in the intake. considering I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant approaching 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I give a positive response the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know since I border you? No, I guess that is it.
Its also worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a in poor health pump will all upshot in insufficient fuel subconscious delivered to the engine. Might after that be worth cleaning out the idle quickness run motor / valve as these acquire clogged going on next carbon and some brake cleaner washed through helps forgive things off.
