I have a 2004 ES330 bearing in mind a hestitation problem. It is fine from a full stop but in imitation of I go nearly turns on onto highway ramps, similar to I pain 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 in the manner of the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery thoroughly charged? With or without headlights on. Relatively new 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 links in the intake. subsequently I put my Turbo OBDII app on, everything seems good except that the TPS stays constant something like 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I assume the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know in the past I be close to you? No, I guess that is it.
Its afterward worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will all upshot in insufficient fuel monster delivered to the engine. Might afterward be worth cleaning out the idle quickness direct motor / valve as these acquire clogged up subsequent to carbon and some brake cleaner washed through helps forgive things off.
