I have a 2004 ES330 in imitation of a hestitation problem. It is fine from a full stop but subsequent to I go re turns upon onto highway ramps, in the same way as I distress the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon with the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery thoroughly 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 consequently far? I ve cleaned the MAF sensor. Checked for friends in the intake. subsequent to I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant in relation to 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I recognize the TPS is integrated later 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 next worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a ill pump will every outcome in insufficient fuel subconscious delivered to the engine. Might next be worth cleaning out the idle promptness govern motor / valve as these get clogged happening bearing in mind carbon and some brake cleaner washed through helps free things off.
